C Correct answer
Explanation

Correct. The four words - leaf, life, knife, and self – follow the same rule while forming the plurals (change –f or –fe into –ves). Thus, the plural forms of these words are – leaves, lives, knives and selves. The word ‘roof’, though ending with –f, is an exception. The plural of roof is roofs.
