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

\newline

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

Reason (R): Air inside rushes out on breaking

\newline

This is FALSE because:

\newline

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

\newline

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

\newline

This rapid inrush of air causes the bang sound

\newline

The direction stated in R is opposite to what actually happens
