Correct option is A
The correct substitution of the highlighted segment is (a)
farther.
· The word
"farther" is the correct comparative form of "far" when referring to physical distance. The phrase
"more farther" is incorrect because "farther" already implies a comparison, so the word "more" is redundant.
·
Grammatical rule used: When comparing distances, "farther" is used as the comparative form of "far." It should not be preceded by "more."
·
Example: "The park is farther from my house than from the school." Here, "farther" correctly indicates the comparative distance.
