Answer 1

The correct answer is at the sphere of knowledge.

Key Points

'At' should be replaced by 'in'.
At is used when you are at the top, bottom, or end of something; at a specific address; at a general location; and at a point.
'In' means forming a part of something.
- For Example - I've been waiting in this queue for ages.
The use of 'at' is incorrect here.
Thus, the option that contains grammatical error is option 4.

Correct Sentence: During the seventeenth century, there were great developments in the sphere of knowledge.
