The POP H instruction in the 8085 copies the top of stack to the HL register and then increments the stack pointer by 2. In C pseudo code, the sequence is L = *(SP++); H = *(SP++);

What will be the addressing mode of instruction POP D in microprocesser 8085?
Stack/explicit.
What are the instruction to reset RST 7.5?
To reset the pending RST 7.5 instruction in the 8085, you need to execute a SIM instruction with a particular value in the accumulator. PUSH FLAGS MVI A,10H SIM POP FLAGS Of course the PUSH and POP are optional, if you don't need to preserve the value of the accumulator.
What will happen when pop instruction is executed?
The top of stack to copied to the specified register and the stack pointer is incremented by 2. A special form of POP, RET, has the program continuing with the popped address in the program counter, i.e. a return from subroutine or function call.
What is the similarity between call-return and push-pop instruction?
If this is a homework assignment, you really should try to answer it on your own first, otherwise the value of the reinforcement of the lesson due to actually doing the assignment will be lost on you.The call-return and push-pop instruction sequences on the 8085 are similar in that each pushes something on the stack and then pops something off the stack.In the case of call-return, that something is the program counter. In the case of push-pop, that something is up to the programmer, and it can be one of AF, BC, DE, or HL.
Possibe way of implementing ret instruction in 8085 if ret insruction was not present?
You would have to pop the stack into two dedicated memory locations in RAM, saving and restoring the register(s) used to do that, prefix those two locations with a JMP opcode, and JMP to the JMP.

Timing diagram of pop b instruction on 8085 microprocesser?
