• A. a-iii, b-iv, c-i, d-ii
• B. a-iii, b-iv, c-ii, d-i
• C. a-ii, b-iii, c-i, d-iv
• D. a-iii, b-i, c-iv, d-ii

Answer 1

The correct option is B a-iii, b-iv, c-ii, d-i

$\bullet$ Cuscuta is a parasitic plant. It lacks chlorophyll and grows on other living plants (host) and derives nutrition from them. This results in weakening of the host plant.
$\bullet$Insectivorous plants have chlorophyll and can produce their own food. But they grow on nitrogen-deficient soil. So, to compensate for this nitrogen deficiency they feed on insects. E.g., Pitcher plant and venusflytrap.
$\bullet$ Lichen is the symbiotic association between algae and fungi. Here the algal component prepares food for the fungi. In return fungi provides protection to the algae partner.
$\bullet$Saprotrophs do not contain chlorophyll and cannot produce their own food. Instead, they grow on dead and decaying matter and obtain nutrients from them. E.g., Mushroom, yeast, mold, etc.
