Concept:An antonym is a word that means the opposite of another word.
Here, we must find the option that is most opposite in meaning to the underlined word "repulsed".
Explanation:"Repulsed" means to be filled with disgust or to be strongly turned away by something.
A person who is repulsed experiences strong dislike or revulsion.
Now let us examine each option carefully.
Option A, "repelled", means driven back or disgusted, so it is very close in meaning to "repulsed", not opposite.
Option C, "irated", means made angry or annoyed, which is not a direct opposite of feeling disgust.
Option D, "shocked", means surprised or deeply disturbed, and it does not carry the opposite meaning of repulsion.
Option B, "gratified", means pleased, satisfied, or greatly delighted.
This pleasant feeling is exactly the reverse of the strong disgust expressed by "repulsed".
Therefore, "gratified" is the correct antonym among the options given.
Answer:B. gratified
