Correct option is A
The sentence is in the
third conditional form, which is used to talk about hypothetical or unreal situations in the past. In this case, the condition "If I had been there" refers to an unreal past event, so the correct structure for the result clause should be
"would have + past participle". Hence, the correct phrase is "I would surely have solved."
Grammatical rule used: In third conditional sentences, the structure is:
·
If + past perfect (had + past participle) for the condition
·
Would have + past participle for the result.
Example:
· Incorrect: If I had studied harder, I would pass the exam.
· Correct: If I had studied harder, I would have passed the exam.
Thus, the sentence should be: "If I had been there, I would surely
have solved the problem for you."
Other options are incorrect because:
·
(b) "I will surely solves" is grammatically incorrect and uses future tense, which does not fit the past hypothetical scenario.
·
(c) "I would surely solving" is incorrect because "solving" should not follow "would" in this context.
