Question 8

+2 marksOne correct option

Consider the tables 1 and 2 below consisting of mathematical statements / questions (Table 'Statement (S)') and answers (Table 'Answer (A)'). Answer the given subquestions based on the tables.

Consider the possible mapping between the columns 'Statement(s)' and 'Answer(A)'. The labels of each element in S and A are marked by S1-S5 and A1-A4. Which one of the following options is correct?

  1. A

    The functional mapping from S to A is one-one but not onto

  2. B

    The functional mapping from S to A is onto but not one-one

  3. C

    The functional mapping from S to A is bijective

  4. D

    The functional mapping from S to A is neither one-one nor onto

  5. E

    None of these: The mapping from S to A is not a function
