His ___ to help us was greatly appreciated. (WILL)

Answer and explanation

Correct answer: A. willingness

  1. Step 1: Work out which part of speech the gap needs. Step 2. After 'His' and before 'to help' we need a noun: 'willingness'. Answer: willingness. Why not the others: 'Willing' and 'unwilling' are adjectives, and 'willingly' is an adverb.
