Correct option is B
· Scientific reviews describe
sunflower seed protein content typically in the range of about 16–19% of the seed.
· Feed composition tables show crude protein values commonly around
15–20% for whole sunflower seed, depending on variety and conditions.
Why other options are wrong
· (a)
5–8% – far below observed ranges for sunflower; such low protein is more typical of some starchy grains, not oilseeds.
· (c)
35–40% – this is closer to protein content of
sunflower meal/cake after oil extraction, not whole seed.
· (d)
50–60% – unrealistically high for sunflower; such levels are closer to highly concentrated protein isolates, not normal seed.
