d. Frustrate

Answer 1

Hint : Thwart is an action to prevent (someone) from accomplishing something.

Complete step by step solution :
Thwart is to stop something from happening or someone from doing something. For example : he never did anything to thwart his father.
Let us examine all the given options to find out the correct answer :

Option ‘a’ is Favour. It is an approval, support, or liking for someone or something ; the act of kindness beyond what is due or usual. For example : I've come to ask you a favour.

Option ‘b’ is Sustain. It means to strengthen or support physically or mentally; undergo or suffer. For example : he sustained severe headaches.

Option ‘c’ is Promote. It means to support or actively encourage/further the progress of someone or something ; raise someone to a higher position or rank. For example : she was promoted to General Manager.

Option ‘d’ is Frustrate. It means to prevent (a plan or attempted action) from progressing, succeeding, or being fulfilled. For example : the rescue attempt was frustrated by bad weather.
We can now easily figure out the correct answer. The correct antonym of thwart is promote. Hence, the correct answer is option ‘c’, promote.

Note : Don't get confused between "promote" and "favour", they both may seem as the antonym of "thwart" but only "promote" is the correct answer.
