• B. Only (a) and (b)
• C. Only (a) and (c)
• D. All (a), (b), and (c)

Answer 1

The correct option is A Only (a)

Plant roots respire at a lower rate compared to animals because these lack specialised cells like stomata/lenticels, which are present on other parts of the plant. Animals too have specialised systems for respiration.

Thus, Option A is correct.
