You might spot a tiger in the Sariska reserve if you would be lucky.

Correct option is A

The correct substitution is (a) if you are.
Explanation:
The phrase “if you would be lucky” is grammatically incorrect. In a first conditional sentence, we use present simple in the “if-clause” and modal verb (might/will/can) in the main clause.
Correct structure:
· Main clause: You might spot a tiger
· If-clause: if you are lucky
Grammatical Rule Used:
· First Conditional Rule:
· If + present simple, → will/can/may/might + base verb
· “Would” is not used in the "if" clause of first conditionals.
Correct sentence:
You might spot a tiger in the Sariska reserve if you are lucky.
Example:
· If you are careful, you might succeed.
