(a) Remains same

(b) Decreases

(c) Increases

(d) Is not proportional

This question was posed to me in an international level competition.

This interesting question is from Datagram Networks in division Network Layer of Computer Network

Answer 1

Correct answer is (c) Increases

To elaborate: Probability of the error in a transmitted block increases with the length of the block. Hence, the blocks should be as short as possible for ideal transmission with low possibility of an error.
