Detailed explanation please: A or B. Thank you

gvij2017 · Answer

Grammatically I don't see any error in A and B. Both are correct in their construction. 
Even I also seek clarification for A over B.

Hi,

We can also make conditional clauses without if.

Study the examples given below.
 
 If I had known his real motive, I wouldn’t have supported him.
We can express the same idea without if.

Had I known his real motive, I wouldn’t have supported him .

In B, 'If' clause is unnecessary, though it's not incorrect, A is short and precise.

Option A and B seems to be identical.  Bunuel   EMPOWERgmatVerbal 
 please help us understand the difference between two options.

Gaurav2896 · Answer

The option B is not conditional , for conditional checkup try reversing the sentence by adding 'if' in second part. If sentence works it is conditional .
For eg : - The physicians explained that if the patient had known the warning signs of cancer, he would have come in earlier --> make sense.
Now reverse : - the physicians explained that if the patient had come earlier , he would have known the warnign signs of cancer --? doesnt makes sense , so A

Official Explanation

(C)  and  (E)  are incorrect because the clause expressing past condition contrary to fact requires past-perfect subjunctive  (“had known”) .

(D)  is incorrect because the clause stating a possible conclusion requires the perfect form of a modal auxiliary  (“would have come”) .

(A)  and  (B)  both use the correct verb forms in both clauses but (B) adds  “if ” ; this word is superfluous and alters the word order required by Standard Written English.

The correct answer is (A).

CEdward · Answer

A and B are both correct. However, A is punchier and cleaner. It's perfectly acceptable to place the 'effect' (then) part of the if/then construction prior to the 'condition' (if).
