Choose the most suitable option to replace the highlighted part of the sentence:
The sun is shining bright but it will be possible to go out for a walk.
Show answer & explanation
Correct answer: A
Explanation
The original sentence uses 'but,' which indicates a contrast between two ideas: the sun is shining bright, and it will be possible to go for a walk. These ideas are not in contrast; rather, the first statement (sun is shining) is the reason or cause for the second (going for a walk). The word 'so' is used to show cause and effect, making it the most suitable replacement to logically connect the two clauses.
