Answer:
Firstly, perform the necessary operations.
12.637 - 2.42 = 10.217
However according to the rule of significant figures and rounding off, whenever we add such numbers and units, we must look at the least number of decimal places and round it off to that digit.
Hence 10.217 can be written as 10.22 because if you drop 7, add +1 to the previous digit.
Hence answer is c)10.22
