The Fahrenheit scale formula is F = (9/5)*C + 32.

Firstly, we must identify the significant figures in the given temperature value: 7.02F1F1F1S1F1F1F10C.

There are 6 significant figures: 7.02, F1F1F1S1, F1F1F1, and 10.

Converting to Fahrenheit:

F = (9/5)*C + 32
F = (9/5)*10 + 32
F = 50 + 32
F = 82

The Fahrenheit value has two significant figures: 82.

Therefore, the answer is B) 2.
