The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments, is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: Over the past five decades, term deposits in banks have emerged as the primary instrument of financial savings for the average Indian after former premier Indira Gandhi embarked on a mission to nationalise the lenders - 14 in the first tranche - on a rainy afternoon in July 1969. Coming with an unsaid sovereign guarantee of sorts, fixed deposits (FDs) seemingly offered investors liquidity - and safety - as nationalisation sought, in part, to arrest the 40-odd bank failures a year.  Now, however, deposits must burnish their allure to retain leadership status in an increasingly crowded financial marketplace that offers choice. Why? Arguments: I. If FDs are giving 7.5% and the effective tax rate is 10%, one gets close to 5-5.2% return. Similarly, in the case of FMP, if the rate is 7.5%, effective taxation comes to 10%, one gets 6.75%. It is higher than the effective returns on bank deposits.  II. People are becoming aware of more asset classes that offer better returns, and the quest for such assets became more pronounced after interest rates fell substantially over the past four years.  III. Savers are looking at mutual funds and provident funds for the higher return.

Crude mineral oil comes out of the earth as a thick brown or black liquid with a strong smell. It is a complex mixture of many different substances, each with its own individual qualities. Most of them are combinations of hydrogen and carbon in varying proportions. Such hydrocarbons are also found in other forms such as bitumen, asphalt and natural gas. Mineral oil originates from the carcasses of tiny animals and from plants that live in the sea. Over million of years, these dead creatures form large deposits under sea­bed and ocean currents cover them with a blanket of sand and silt. As this material hardens, it becomes sedimentary rock and effectively shuts out the oxygen, thus preventing the complete decomposition of the marine deposits underneath. The layers of sedimentary rocks become thicker, and heavier. Their pressure produces heat, which transforms the tiny carcasses into crude oil in a process that is still going on today.
The time taken for the marine deposits to harden into rocks is
