Correct Answer: Blow

Solution : The correct option will be the first option.

In this context, blow is used to describe the forceful movement of the wind against the window. Both "gust" and "blow" can convey the idea of impact or force, but in this case, "blow" is a more fitting synonym as it specifically relates to the action of the wind.

The meanings of the other words are as follows:

• Cramp: It means experiencing such a muscle contraction.
• Feel: It denotes a particular sensation or impression.
• Pump: It means a device for moving fluids, e.g., the heart.

Therefore, the correct option will be blow.
