Question

what is the meaning of placid? serious danger; not clear; hard to see through; calm and peaceful; strength and energy

Explanation:

To determine the meaning of "placid", we analyze each option: "Serious danger" is incorrect as "placid" relates to calmness. "Not clear; hard to see through" describes something opaque, not "placid". "Strength and energy" is unrelated to the meaning of "placid". The correct meaning of "placid" is calm and peaceful, so the option "Calm and peaceful" is correct.

Answer:

C. Calm and peaceful (assuming the orange option is labeled C; if labels are A - D with A: Serious danger, B: Not clear; hard to see through, C: Calm and peaceful, D: Strength and energy, then the answer is C. Calm and peaceful)
