Best answer
The correct choice is (b) double precision floating point

The best I can explain: The numbers according to international IEEE 754 standard are stored as a double precision floating point. It stores the numbers in 64-bit format, stored in bits from 0 to 51, exponent in bits is from 52 to 62 and signs in a bit is 63.
