D Total parasites grow in waterlogged environments, while partial parasites grow in dry soil.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 20 states: 'Total parasites (e.g. dodder, broomrape) are never green, hence, they cannot manufacture their own food. They draw all their nourishment from the host plant.' It also mentions, 'Partial parasites (e.g. Mistletoe) are green, therefore, they are not entirely dependent on the host plant.'

Hint

Consider the presence or absence of chlorophyll.
