Select the most appropriate option to fill in the blank.

The party was a ____ hour for everyone, except Mukesh.

happy

The most appropriate option to fill in the blank is happy.

The sentence is about a party that everyone enjoyed except Mukesh. The word "happy" means feeling or showing pleasure or contentment. It is the most appropriate word to use in this context, as it describes the general mood of the party and the contrast with Mukesh's mood.

The other options are not as appropriate:

• Welcome means greeted in a friendly and enthusiastic way. It would not be accurate to use "welcome" in this context, as the party was not a welcome event for Mukesh.
• Dry means not containing or having any liquid. It would not be accurate to use "dry" in this context, as the party was not a dry event.
• Stable means not changing or fluctuating. It would not be accurate to use "stable" in this context, as the party was not a stable event.
