Who is hamlet forced to kill to save his own life? rosencrantz and guildenstern claudius and laertes polonius and claudius polonium and gertrude

The correct answer is A. Rosencrantz and Guildenstern.

Explanation:

Even though Hamlet's two friends are sycophants corrupted by Claudius's power and influence, he had never planned to kill or harm them in any way. He only does it when he discovers that they were on a secret mission to deliver him to the English king so that he could be executed.

So, Hamlet forges the letter they were carrying and enters their names instead of his own. He does it to save his own life and, in a way, to punish them for their dishonesty.
