Answer: B. Daylight savings time is the best time because it is no longer dark in the mornings ; it is light .
============================================================
Explanation:
An objective statement simply mentions a fact that can be verified to be true (or proven to be false). One often used example could be something like "the sky is blue" or you could go for something more complex.
In contrast, a subjective statement is an opinion. Phrases like "I feel" or "I believe" or "I think" are often tied to subjective opinions as they express a point of view. In the case of choice B, the author is stating how they believe daylight savings is the best time because it's no longer dark in the mornings and there is (a bit of) light instead. There's nothing inherent about a dark morning being bad, versus a dark morning being good. It's all a matter of subjective opinion on what you prefer.
Choices A, C and D are objective facts. Choice A mentions the timing of daylight saving when it starts/ends. Choice A is a bit vague, but it gets the right timeframe, so it's an objective statement. Choice C mentions a historical fact, and the same applies to choice D, which is why those are objective statements as well. All of this means we can rule out choices A, C and D.
