Correct option is B
Option (b) contains an error.
Error Explanation: The preposition “between” is used to indicate a relationship
between two entities, not more.
However, the term “executive members” implies
more than two people, so the correct preposition should be
“among.”
Correct sentence:
There is constant friction among the executive members of the Association.
Grammatical Rule Used:
· Use
“between” when referring to two people/things.
· Use
“among” when referring to more than two people/things collectively.
Example:
• There is misunderstanding between John and Mary.
• There is good coordination among the team members.
Information Booster: If we are referring to individual relationships
between each member in a group of more than two, “between” can sometimes be used—but in general usage like this,
“among” is appropriate.
