Answer 1

Correct option is (a) [digits][.digits][(E|e)[(+|-)]digits] The explanation is: Floating-point literals may also be represented using exponential notation: a real number followed by the letter e (or E), followed by an optional plus or minus sign, followed by an integer exponent. This notation represents the real number multiplied by 10 to the power of the exponent.
