Topic: Degree of Comparison,

Best Answer Explained in Below-:

The phrase “The richer, the more friends he has” employs a common English structure known as a comparative correlation, which expresses a relationship between two variables—in this case, wealth and the number of friends. This structure typically uses the "the ... the ..." format to illustrate that as one factor increases (richer), the other factor also increases (more friends).

Option A, “The richer, the more friends he has,” correctly maintains this comparative structure by consistently using the definite article "the" before both adjectives, "richer" and "more." It clearly indicates that an increase in wealth is directly correlated with an increase in friends.

In contrast, options B and C lack the appropriate grammatical structure. Option B, “Richer, more he has friends,” sounds awkward and fails to establish a clear relationship. Option C, “Richer, more friends he has,” while closer, still lacks the necessary correlation format.

Option D, “The richer, the more he has friends,” while structurally parallel, makes a slight grammatical error by using “has friends” instead of the more fluid “friends he has.”

Ultimately, option A is the clearest and most idiomatic choice, effectively conveying the relationship between wealth and social connections.
