Which of the following statements regarding binary counters are correct? (a) Clock inputs of all the flip - flops of a synchronous counter are applied from the same source whereas those in an asynchronous counter are from different sources. (b) The asynchronous counter has ripple effects whereas the synchronous counter does not. (c) Only J-K flip-flops can be used in synchronous counters whereas asynchronous counters can be designed with any kind of flip flops. (d) Latches can be used for designing asynchronous counters.

Given is a statement followed by two assumptions numbered I and II. Consider the statement and the following assumptions and decide which of the assumptions is/are implicit in the statement. Statement: Sustainability can be defined as the practice of meeting the needs of the current generation without degrading or destroying the natural resources (e.g. water, soil, biodiversity, oil, minerals.) Assumptions: Our lives and economies are dependent on natural capital, which is made up of these natural resources and natural services, and the energy provided by the sun. Just as every investor knows, we should invest our capital and live off on the interest, it provides. To live sustainably, we need to do the same: protect our natural capital and live off our biological income.
Workmen arrive at a mine workshop to receive tools for maintenance. The inter-arrival time of workmen at the service counter is exponentially distributed with an average time of 10 min. The service time at the counter is also distributed exponentially with a mean time of 6 min. The probability that there is a queue (more than one workman) at the service counter is,
The process of burial is the ritual act of placing a dead person or animal into the ground. Humans have been burying their dead for at least 100,000 years. Alternatives to burial may include cremation, promession and others. There are many environmental benefits of natural burials as the bodies are bio degraded and add many benefits to the soil and over several years tend in helping in the formation of petroleum. But there are few issues with natural burials few of which are mentioned below. Which of the following, if true, would strengthen the conclusion about the issues with natural burials? 
Mark the incorrect proposition:
1. Set-off is a statutory defence to a plaintiff's action, whereas a counterclaim is a cross-action.
2. Set-off and counter-claim arises out of the same transaction.
3. Set-off should not be barred on the date of the suit while counter-claim should not be barred on the date of filing of written statement.
4. Claim for set-off cannot exceed plaintiff's claim, whereas counterclaim can exceed the plaintiffs claim.
5. Both set-off and counter-claim cannot exceed the pecuniary jurisdiction of the court.
