Identify the correct conditional sentences in the following.
(a) If she works hard she will secure first position.
(b) If he will take an early bus he will reach Poona in the afternoon.
(c) If you whistled the girls would mind it.
(d) If he would try hard, he would get a first class.
Answer Options:

The correct answer is Option A (Only (a) and (c)).

Key Points:
• Rule: The conditional clause (If-clause) NEVER takes future modals like 'will' or 'would'.
• (a) 'If she works hard [Simple Present], she will secure first position [will + base]' → Correct Type 1 Conditional.
• (b) 'If he will take...' → Incorrect because 'will' cannot be used in the If-clause. It should be 'If he takes...'.
• (c) 'If you whistled [Simple Past], the girls would mind it [would + base]' → Correct Type 2 Conditional.
• (d) 'If he would try hard...' → Incorrect because 'would' cannot be used in the If-clause. It should be 'If he tried hard...'.
• Thus, only (a) and (c) are correct.
• Key Takeaway: Never use 'will' or 'would' in an if-clause: use Present Simple for Type 1, Past Simple for Type 2.
