Answer: Option (a) is the correct answer.
Step-by-step explanation:
Net downward force exerted at the surface of a liquid because of the presence of strong intermolecular forces in the molecules of a liquid present beneath the surface is known as surface tension.
Volatility is the property of a substance to convert readily into vapors or gaseous state from liquid state.
Hence, when molecules of a liquid has weak intermolecular forces then it will have weak surface tension. As a result, it can be converted into vapors easily.
Thus, we can conclude that a liquid that is very volatile is also likely to show weak surface tension.
