• A. He is so weak that he cannot walk without help.
• B. He cannot walk without help because he is too weak.

• D. No change

Answer 1

Answer: (C)

He is too weak to walk without help.

An infinitive form is to+verb in the present tense. Here, the main verb is walk and infinitive is "to walk". Hence, Option C is correct. The rest of the options do not adhere to the goal, hence incorrect.
