Question consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:
Question consists of two statements, namely, Assertion (A) and Reason (R). For selecting the correct answer, use the following code:

(a) Both Assertion (A) and reason (R) are true and Reason (R) is a correct explanation of
Assertion (A).
(b) Both Assertion (A) and reason (R) are true and Reason (R) is not a correct explanation
of Assertion (A).
(c) Assertion (A) is true and Reason (R) is false.
(c) Assertion (A) is false and Reason (R) is true.

The correct answer is: (a) / (b) / (c) / (d)
Sol:
(b) Both assertion (A) and reason (R) are true, but reason (R) is not a correct explanation of
assertion (A).
Clearly, reason (R) is true.
The maximum frequency is 23 and the modal class is 12 – 15.

∴ Assertion (A) is true.
However, reason (R) is not a correct explanation of assertion (A).
