India has too often to fulminate against Pakistan’s role in aiding and abetting acts of militancy on her soil.

The correct answer is D. protest.

To fulminate means to express strong disapproval or condemnation. In this case, India is expressing strong disapproval of Pakistan’s role in aiding and abetting acts of militancy on its soil.

The other options are incorrect because they do not accurately reflect the meaning of the word fulminate.

• Think: to form or have an opinion or idea about something.
• Consider: to think about something carefully before making a decision.
• Conspire: to plan together secretly in order to do something harmful or illegal.

In this case, India is not simply thinking about or considering Pakistan’s role in aiding and abetting acts of militancy on its soil. It is protesting against it.
