2. SECTION – I Multiple correct Answers type In each part of the question four alternatives are given of which one or more alternative(s) is (are) correct. Select the correct alternative(s) and write down the corresponding letter(s) a, b, c, d in your answer book against the sub-question number. In your answer the sequence of the sub question marks should be the same as in the question paper. For each subqeustion marks will be awarded only if all the correct alternative and no wrong alternative are selected.
