Given below are two statements:\n Statement I: The ribosomes of chloroplasts are 70S, which are smaller than the cytoplasmic 80S ribosomes of eukaryotic cells.\n Statement II: The inner membrane of the chloroplast is comparatively more permeable to solutes than its outer membrane. \nIn the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.

  4. Statement I is incorrect but Statement II is correct.
