Hard

In this question, there are two statements labelled as Assertive (A) and Reason (R).

Assertion (A): An electric bulb makes a ‘bang’ when it is broken.

Reason (R): The air inside the bulb rushes out immediately on breaking.

A is false but R is true.

A is true but R is false.

Both A and R are true and R is the correct explanation of A.

Both A and R are true but R is not the correct explanation of A.

✅ Correct Option: 2

Assertion (A): Electric bulb makes a 'bang' when broken

This is TRUE since light bulbs do make a bang sound when broken

Reason (R): Air inside rushes out on breaking

This is FALSE because:

A light bulb has a vacuum inside (or inert gas)

When broken, air rushes IN from outside to fill the vacuum

This rapid inrush of air causes the bang sound

The direction stated in R is opposite to what actually happens
