Correct Answer: D
Rationale: In the context of microsurgery, the word 'delicate' refers to the intricate, precise, and fine nature of surgeries performed using microscopy. These surgeries require intricate attention to detail and precision due to the small and delicate structures involved, making 'intricate' the most appropriate synonym. 'Subtle' implies understated or not obvious, 'fragile' suggests easily broken or damaged, and 'refined' refers to something developed or improved over time, none of which fully capture the detailed and precise nature of microsurgery. Therefore, 'intricate' is the correct answer.
