Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Acetylene also called ethyne. Its molecular formula is $C_{2} H_{2}$ . It has one $C - C$ triple bond tha makes it unsaturated and each carbon has one hydrogen attached. $C$ are $s p$ hybridised and therefore the molecule has linear geometry
Assertion and reason are correct and are correlated.
Option A is correct
