For converting a decimal number into octal number, the decimal number is expressed as a series of the type
None of the above
17.
Consider the following statements
- The sign of a floating point number depends on the sign of mantissa only.
- If the absolute value of a number is less than 1, the sign of exponent is zero or positive.
- With sign bit of mantissa as 0, increasing the exponent from a positive to a more positive value gives a larger floating point number.

Assertion (A): In microprocessor 8085 instruction LXIB, 90 FF H means register B and C are loaded with upper and lower bytes to get B = 90 H and C = FFH.
Reason (R): In 8085 the stack pointer indicates which memory location is to accessed.
