d) blinking of eyes

$\Large \text{Explanation \: - }$

• A leaking tap , simple pendulum , shadow of an object during the day are some of the proven method by which we already have measured time .

• But we cannot measure the time by blinking of eye because sometime we blink rapidly and sometimes we blink very slowly .

• it's actually not a periodic phenomenon which have to be repeated after certain period

• It is not time based it is random .

• Hence , we can not measured the time by blinking of eye .
