Spot the error in the following sentence

The correct answer is Option (4) → some had greatness thrust on them

The sentence states a general truth in the simple present ("is often said", "are born", "achieve"), so the last part must also be in the present: have greatness thrust on them.

Option 1: It is often said that — No error.

Option 2: some men are born great — No error.

Option 3: some achieve greatness and — No error.

Option 4: some had greatness thrust on them — Error. The past tense "had" breaks the present tense of the sentence; it should be "have".
Corrected: some have greatness thrust on them

Correct sentence: It is often said that some men are born great, some achieve greatness and some have greatness thrust on them.
Example: Some students have leadership thrust on them when the class monitor leaves.
