Select the option that can replace the highlighted phrase and make the sentence grammatically correct.
"After flip through half dozen profiles with the same name, he chance upon Elina’s profile, he succeed in zeroing in on her now recognisable face."

To correct the sentence, we need to focus on three key grammatical aspects:
1. Gerund vs. Infinitive:
· "After flip" is incorrect. The verb following "After" should be in the gerund form, i.e., "After flipping."
2. Correct Use of Article & Plural Noun:
· "Half dozen profiles" → Should be "half a dozen profiles" to maintain correct article usage.
3. Correct Tense Usage:
· "Chance upon" should be in the past tense as the sentence describes a past action. The correct form is "chanced upon."
· "He succeed" should also be changed to "he succeeded" for past tense consistency.
Applying the Rules:
The sentence should read:
"After flipping through half a dozen profiles with the same name, he chanced upon Elina’s profile, he succeeded in zeroing in on her now recognisable face."
Other options:
· (a) "flip through half dozen profile, he chance, he succeeded" → Incorrect as "flip" should be "flipping" and "profile" should be plural.
· (c) "flipping through half dozen profiles, he chanced, he succeed" → Incorrect as "succeed" should be "succeeded."
· (d) "flipping through half dozen profile, he chance, he succeeded" → Incorrect as "profile" should be plural and "chance" should be past tense.
Thus, the correct answer is (b) "flipping through half a dozen profiles with the same name, he chanced upon Elina’s profile, he succeeded."
