Option 1 -> "Yama" is the god of death, and "wresting the prize" (the patient's life) symbolizes Dr. Raman's tireless fight to save patients from dying.
Option 2 -> The passage emphasizes his dedication to patients and truthfulness, not any pursuit of fame or greed.
Option 3 -> There is no mention of competition with other doctors; the focus is entirely on his relationship with patients and death.
Option 4 -> The reference to Yama is metaphorical, not literal; Dr. Raman is a practical, scientific doctor using symbolic language.
Hence, Option 1 -> The metaphor vividly captures how Dr. Raman, when he sees even the faintest hope, battles relentlessly (sometimes for "hours or days") to save his patients from death, personified as Yama in Hindu mythology -> correct
