In the RCL instruction, the contents of the destination operand undergo function as

(a) carry flag is pushed into LSB & MSB is pushed into the carry flag

(b) carry flag is pushed into MSB & LSB is pushed into the carry flag

(c) auxiliary flag is pushed into LSB & MSB is pushed into the carry flag

(d) parity flag is pushed into MSB & LSB is pushed into the carry flag

This question was posed to me in an interview for job.

Question is taken from Instruction Set of 8086/8088 in division 8086/88 Instruction Set and Assembler Directives of Microprocessor

Correct option is (a) carry flag is pushed into LSB & MSB is pushed into the carry flag

Easiest explanation: In RCL(Rotate right through carry), for each operation, the carry flag is pushed into LSB and the MSB of the operand is pushed into carry flag.
