Correct option is D
The correct substitution of the highlighted words is
"is a good place to study".
The phrase
"to studies" is incorrect because
"to" should be followed by the
base form of the verb (study). The correct sentence is
"The library is a good place to study because it is very quiet."
Grammatical rule used:
After "to" (infinitive marker), we always use the
base form of the verb (study), not its plural or conjugated forms.
Explanation in Hindi:
"To" (infinitive) के बाद क्रिया का मूल रूप (base form) आता है। इसलिए "to studies" गलत है और सही वाक्य
"to study" होगा।
