Naveen is so lazy that he .......

The sentence structure "...so lazy that..." requires a negative consequence of Naveen's laziness.

Only option c logically completes this, as "Can seldom complete his work on time" is a direct result of laziness.

The other options fail to complete the sentence because  "Cannot depend on others" (option A) is not related to laziness; "Cannot delay work"(option B) has an opposite meaning (implies discipline); and  "Dislike to postpone work" (option D) contradicts laziness (implies eagerness).

Correct Sentence is therefore  "Naveen is so lazy that he can seldom complete his work on time." which means option C is the correct choice.
