A is correct: Vitamin B12 assists in producing red blood cells to transport oxygen to working muscles, making it especially important for endurance athletes.

Other options:

B is incorrect: Calcium plays a role in muscle contraction and nerve impulses, not red blood cell production.
C is incorrect: Iron makes haemoglobin within red blood cells but doesn’t produce the actual blood cells.
D is incorrect: Vitamin D supports bone health and immune function, not red blood cell production.
