Which word completes the sentence: 'This is to c______ that we are ready to go along with your proposal.'

• A. Conform
• B. Confide
• C. Consume
• D. Confirm

Answer: (D)

The idea being tested is choosing a verb that expresses formal verification or affirmation in a business sentence. In this context, the phrase should show that you are confirming your agreement to proceed with the proposal. The word that fits best is confirm because it means to verify or affirm something. So the sentence reads naturally as: "This is to confirm that we are ready to go along with your proposal." It clearly communicates that you agree to move forward.

The other options don’t fit the sense of affirmation. Conform would imply aligning with a standard or rule, which doesn’t suit the idea of confirming readiness. Confide means to share secrets or trust someone with information, which is inappropriate here. Consume means to eat or use up, which also doesn’t match the meaning of confirming readiness to proceed.
