She did not sing so . . . . . . . . as her friend. A. good B. better C. best D. well

good
better
best
well

The correct answer is: A. good

The other options are:

  • B. better: This is incorrect because it implies that she sang better than her friend.
  • C. best: This is incorrect because it implies that she sang the best out of everyone.
  • D. well: This is incorrect because it is a vague word that could mean many things.

The word “good” is the most accurate word to describe her singing because it is a neutral word that does not imply anything about her singing ability.
