sole factor in the ____________ of the parent properties

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3, i.e. preservation.

  • Since the given statement uses 'of' it indicates a relationship between a part and a whole. So, it is evident that the blank will constitute a noun because a noun will signify itself as a part of the whole that is 'parent properties'. For this instance, the correct answer is preservation since it is a noun. The rest of the options imply itself as verbs and hence becomes incorrect.
