Choose the correct sentence:

Correct option is C

The correct answer is option (c).

In First Conditional sentences, which describe real or possible situations in the future, the structure is:

If + Simple Present, will + base verb

So the correct sentence should be: If I win a lottery, I will buy a car.

Grammatical Rule Used:

In English:

In a First Conditional, the “if” clause takes the Simple Present Tense, and the main clause takes “will + base verb.”

In Hindi:

यदि वाक्य भविष्य में किसी संभावित स्थिति को दर्शाता है, तो "if" वाले भाग में Present Simple Tense और मुख्य वाक्य में will + क्रिया का प्रयोग होता है।

उदाहरण: अगर वह मेहनत करेगा, तो पास हो जाएगा।

If he studies, he will pass.

Examples for clarity:

• Incorrect: If she will call me, I will answer.
• Correct: If she calls me, I will answer.

Meanings of the other options and why they are incorrect:

▪ (A) If I will win a lottery

English: Incorrect use of “will” in the if-clause.

Hindi: "If" वाले भाग में "will" का प्रयोग नहीं होता।

▪ (B) If I am win a lottery

English: “am win” is grammatically incorrect; a helping verb cannot be used like this.

Hindi: "am" और "win" का एक साथ प्रयोग गलत है।

▪ (D) If I would win a lottery

English: “would” is not used in the if-clause of first conditionals.

Hindi: “Would” का प्रयोग “if” वाले भाग में नहीं होता है; यह द्वितीय या तृतीय conditional में होता है।
