CorrectNot quiteAnswer B

Correct answer: B

The normal curve is bell-shaped and symmetric about the mean $\mu$ , so its mean, median and mode coincide.
Its tails come ever closer to the axis but never meet it.

Worth noting

Beyond three standard deviations the curve is very close to the axis, but it never touches it.
