He is one person, I count . . . . . . . . in times of difficulty. A. at B. in C. with D. on

The correct answer is: C. with

The word “with” is used to indicate that someone is close to you and that you can rely on them. In times of difficulty, it is important to have people who you can count on to support you. The word “with” suggests that the person is someone who is there for you and who you can trust.

The other options are not as appropriate in this context. The word “at” is used to indicate a location. The word “in” is used to indicate a time period or a place. The word “on” is used to indicate a surface or a topic.

Here are some examples of how the word “with” can be used in a sentence:

• I count on my friends to be there for me when I need them.
• I’m so grateful to have my family with me through this difficult time.
• I can always count on my dog to make me laugh, even when I’m feeling down.
