See eye to eye

Option B is the correct answer.

"See eye to eye" means to have the same opinion or to agree on something.

The other options don't have the same meaning:
Option A: Staring at each other means looking at someone intensely, which is not what "see eye to eye" implies.
Option C: "Depend on" means relying or counting on someone, which is different from agreeing or having the same viewpoint.
Option D: Making an effort doesn't mean agreeing with someone.
