Select the most appropriate option that can substitute the highlighted segment in the given sentence to improve it. If no improvement is required, select ‘No improvement required’.
We have received no information so far to the main island.

Correct option is D

The correct substitution of the highlighted segment is (d) so far from.
Explanation: The phrase "so far from" is used correctly to indicate a great distance from a specific point or place. The original phrase "so far to the main island" is incorrect because "to" does not appropriately convey the distance aspect. "From" is the correct preposition to use in this context, as it indicates the location from which the information has not been received.
Correct Sentence: We have received no information so far from the main island.
Grammatical rule used: The preposition "from" is used to indicate the starting point of a distance or location in phrases like "so far from."
Example: The village is so far from the nearest town that it takes hours to reach it.
