Answer : 2. "indifferent"
Explanation :

The best option to complete the sentence is B) indifferent.

Here’s the sentence with the correct option:

"The workers are asking for a pay raise, but the management is indifferent to their demands."

Explanation:

Deaf means unable to hear and doesn’t fit the context of ignoring demands.

Indifferent means having no particular interest or concern, which fits well with the idea of not responding to demands.

Resistant implies actively opposing or fighting against, which is more forceful than what the sentence suggests.

Blind typically refers to physical inability to see and doesn’t fit the context here.

So, “indifferent” is the most appropriate choice.
