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: Chat bots and other interfaces are saving employees and HR heads time for more productive activities by providing information and replies to diverse queries or concerns. A few years ago, business communication was driven by multiple faxes in a day and emails were the only quick mode of exchanging information. This information went through the organisation's who's who, while the others were mostly engaged in the daily rut of redundant activities, preventing them from directing their capabilities towards more productive areas. Which of the following arguments brig out the idea that introduction of chat bots and other interfaces is not helping in boosting up the processes? Arguments: I. Using these conversational interfaces, HR departments are successfully aligning themselves with the swiftly-changing organisational processes. These platforms represent people friendly technologies that keep employee experience at the centre, continuously evolving with them.  II. HR technologies are increasingly using advanced machine learning for measuring and analysing workforce engagement. Sentiment analysis is a unique way of gauging an employee's disposition towards the organisation, providing valuable insights essential for improving productivity and predicting attrition rates.  III. The seamless experience chat bots provide makes employees focus on activities that require critical abilities and strategic thinking. Besides enabling HR processes such as generating leave applications and reimbursement forms, the use of chatbots provides quick and smooth access to data from anywhere, anytime.
