It is 64 bits with a range of -2^63 to 2^63 - 1
that is answer is b. 64
Am I correct?
that is answer is b. 64
Am I correct?

Its 8 bytes. [ 64 bits] As double is used to store floating point values and is used in static and constant methods.
@Divisha Madupalli • 12 Feb, 2020
The answer is 8 bytes in a 64-bit system. Double in Java is used for representing the decimal numbers. For double type there are or you can have at least 15-16 bits. The default value for decimals in Java is double if you don't give the specific units. Double uses 1 bit for sign, 11 bits for exponent and 52 bits for the mantissa. A value having a range within 1.2E-38 to 3.4E+38 can be assigned to float variables.

In java,double uses 8 bytes of memory ,which is equal to 64 bits , since 1byte=8 bits.
