Explanation

Why (d) is correct

All three statements are true. Photorespiration happens in the daytime (it needs light-driven RuBisCO activity), it is a feature of C3 plants, and it involves chloroplasts, peroxisomes and mitochondria.

Why the other options are wrong

  • (a) · your answer This is true, but so are (b) and (c), so "all of these" is the best answer.
  • (b) · your answer True, but not the only correct statement.
  • (c) · your answer True, but not the only correct statement.
NCERT point: C4 plants avoid photorespiration.
