The quality of students of an educational institute is of great importance and a crucial starting point.

Correct option is B

The correct substitution of the highlighted segment is (b) The quality of students in an educational institute is of great importance and a crucial starting point.
The preposition “in” is more appropriate than “of” when referring to students within an educational institute. Also, the phrase “is of great importance” is correct and idiomatic. The phrase “a crucial starting point” fits naturally without needing an extra verb like “is” again before it.
So, the sentence should be: “The quality of students in an educational institute is of great importance and a crucial starting point.”
Grammatical rule used:
Preposition Usage and Sentence Parallelism –

2. When two noun phrases are joined by “and” and share the same verb, the second verb is not repeated to avoid redundancy (i.e., no need to repeat “is” before the second noun phrase).
Explanation of the grammatical rule in Hindi:

3. गलत – The quality is important and is a starting point.
4. सही – The quality is important and a starting point.
Example:
The leadership in an organisation is of great importance and a crucial factor in its success.
