Answer : 4. "Both B and C"
Explanation :

The underlined part of the sentence is grammatically incorrect. The preposition 'for’ used here is wrong. The correct preposition should be 'to’. 

Gauge means to judge or assess (a situation, mood, etc.). 

Hence 'assess’ is a synonym of 'gauge’. 

Both choices B and C are correct. Hence the correct answer is option 4.
