The correct answer is: A. Poor.
Wretched is an adjective that means “extremely poor or unfortunate.” It can also mean “causing or feeling great pain or distress.”
Poor is an adjective that means “having little or no money or possessions.” It can also mean “of low quality or value.”
Foolish is an adjective that means “lacking good sense or judgment.” It can also mean “acting in a silly or irresponsible way.”
Insane is an adjective that means “having a severe mental illness.” It can also mean “extremely foolish or reckless.”
Strained is an adjective that means “under great pressure or tension.” It can also mean “not natural or relaxed.”
Transfer is a noun that means “the act of moving someone or something from one place to another.” It can also mean “the act of changing ownership or possession.”
In this case, the word “wretched” is used to describe someone who is extremely poor or unfortunate. The other options do not accurately describe someone who is wretched.
