Solution

The correct option is A Both (i) and (ii) are true and (ii) is reason for (i)
In Searle's experiment, after every step of loading, one waits for sometime (2 or 3 min) before taking reading. This statement is true because in this time interval the wire becomes free from kinks, so that it can get desired length. The vertical oscillations in the wire also subsides in this time interval. So both statements are true and and (ii) is the correct reason for (i).
