Show answer & explanation

Correct answer: C

1. MVI A, 30H: Loads immediate value 30H into the Accumulator (A = 30H). 2. ACI 30H: Adds immediate value 30H to Accumulator with Carry (A = 60H). 3. XRA A: Exclusive ORs Accumulator with itself, resulting in 00H (A = 00H). 4. POP H: Pops stack content into HL pair, does not affect Accumulator. The final content of the Accumulator is 00H.
