Can anybody help me with an explanation
Firstly, the question needs to start with "The lime tree" and not just "The tree".
Moving on, the question merely asks which of the answer choices is an apt inference.
A)Lemons are yellowish green in colour.
Incorrect : The passage says nothing about the colour of lemons.
B. Lime is a greenish yellow fruit.
Incorrect : The passage says it is yellowish green when ripe, it might be some other colour when raw. We can't decisively say it is generally a greenish yellow fruit.
C. Tropical countries are less likely to use limes.
Incorrect : Passage says that they are grown in some tropical countries, they might be used there itself, exported, etc., unclear and therefore incorrect.
D. Pruning is used to keep trees shrub-like.
Incorrect : Passage states the opposite.
E. Citric acid has a sour taste.
Correct : [excerpt : There are, however, some varieties so lacking in citric acid that they are known as sweet limes.] The passage states that varieties that lack citric acid are called sweet limes, implying that the ones with a good quantity of citric acid are sour.
