Tumors are groups of abnormal cells that form lumps or growths, generally without inflammation; the benign tumors are not cancerous whereas the malignant tumors are; the
presence of premalignant tumors is often indicative of precancerous conditions and has the potential to develop into cancer.Semicolon is used - in big lists/nested lists akin to comma or
- to join Independent clauses.
Here, three clauses are joined by semicolon.
Since the first two clause begin with Tumors - the third clause should also begin with tumor to maintain parallelism -
A, B and C are out
b. presence of premalignant tumors are often indicative of precancerous conditions and has the potential to develop into cancer
presence is singular; are is plural - incorrect
d. premalignant tumors are often indicative of precancerous conditions and their presence has the potential to develop into cancer
e. premalignant tumors are often indicative of precancerous conditions and have the potential to develop into cancer
Between option D and E - the only difference is that option D says - the presence of PTs has the potential to develop into cancer(is it the
presence of PTs, which has the potential to develop into cancer? - very subtle difference in meaning compared to option D) while option E says the PTs have the potential to develop into cancer.
Option E seems to be more direct as PTs (if present - which is understood) have the potential to develop into cancer.
Answer E
