Let’s think through this step by step.

The question says:
> The nutrient responsible for immune system boosts is known as vitamin:

And we’re told that the pink flesh (pulp) of grapefruit gives a boost to the immune system. Grapefruit is a citrus fruit — like oranges, lemons, and limes.

We know from basic nutrition that vitamin C is famous for helping the immune system. And where do you get vitamin C? Mostly from citrus fruits!

Now let’s look at the answer choices:

- A. carrots, vision → That’s vitamin A (beta-carotene), not for immunity.
- B. spinach, cell division → That’s folate or iron, maybe B9 — not mainly for immunity.
- C. citrus fruits, immune system → YES! This matches what we know about vitamin C.
- D. milk, bone strength → That’s calcium and vitamin D — for bones, not immunity.

Also, notice in the image, option B is circled — but wait, the letters are mixed up! Let’s read carefully:

The options are labeled strangely:

It says:
- A. D. milk, bone strength → So choice “A” points to “D”
- B. C. citrus fruits, immune system → Choice “B” points to “C”
- C. B₉. spinach, cell division → Choice “C” points to “B9”
- D. A. carrots, vision → Choice “D” points to “A”

But the actual correct *content* is “citrus fruits, immune system”, which is listed under letter C in the content list — and that’s matched with choice B on the left.

So even though it looks confusing, the right pick is the one that says “citrus fruits, immune system” — which is selected when you choose B.

That makes sense because vitamin C comes from citrus fruits and helps your immune system.

Final Answer:
B
