<em />
Explanation:
In the given context, the noun <em>trifle </em>means <em>a thing of little or no importance.</em><em> </em>As a verb, <em>trifle </em>has a fairly similar meaning: <em>to treat without respect or seriousness. </em>If we understand the meaning of this word, we can understand the given excerpt with no problem: people tend to think that the sorrows of children are unimportant compared to those of grown-up people. If someone thinks that, it doesn't mean that it's true. That is why statement A is incorrect. Statement C is not relevant to the given passage, while statement D states the opposite of what the passage says.
