Select the most appropriate option to fill in blank number 1.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. have said.
Tense Concept: The sentence refers to something that has happened repeatedly since a certain point in the past — this calls for the present perfect tense.
Grammatical Explanation:
"Thousands of persons must have said the same thing to her since" is correct because:
"must have said" is used to express a strong assumption about a past action.
The word "since" indicates a time reference from the past up to now, which fits the perfect tense.
Incorrect Options:
said – simple past; doesn't fit with "must" and "since"
says – present tense; grammatically incorrect here
saying – continuous or gerund form; doesn't fit the structure
Final Sentence: Thousands of persons must have said the same thing to her since
Conclusion: The correct answer is have said
