Concept:The correct word should express an excessive interest in other people's private affairs.
Explanation:The sentence describes Kofi as someone who wants to know about everybody's business.
This suggests an unnecessary or overly curious interest in the personal matters of others.
"Friendly" means kind and sociable, but it does not carry the sense of prying.
"Concerned" means worried or interested in a caring way, which is not the intended meaning here.
"Busy" means occupied with activities, not curious about others.
"Inquisitive" means curious or prying, especially about other people's affairs.
The word "too" before the blank shows that the trait is excessive, which fits "inquisitive" perfectly.
