Select the most appropriate option that can substitute the highlighted word segment in the given sentence. If the sentence is grammatically correct, select 'No correction'.
She is attending the conference yesterday.

Correct option is C

The correct substitution of the highlighted segment is (c) attended.
Correct sentence:
She attended the conference yesterday.
Explanation:
The sentence mentions “ yesterday,” which indicates a past action. Therefore, the verb must also be in the simple past tense. “Is attending” is present continuous, which is incorrect for past time references.
Grammatical Rule Used:
When a sentence refers to a specific past time (like “yesterday”), we must use the simple past tense (V2 form).
✦ Explanation in Hindi:
“Yesterday” शब्द बीते समय की ओर संकेत करता है, इसलिए यहाँ क्रिया का रूप “attended” (past simple) होना चाहिए। "Is attending" वर्तमान की क्रिया है जो गलत है।
Meanings of all options:
· (a) No correction – incorrect due to wrong tense. ❌
· (b) has attended – present perfect, needs unspecified past. ❌
· (c) attended – simple past, correct. ✅
· (d) was attending – past continuous, requires background event. ❌
