Answer:
C
Step-by-step explanation:
f"(x) < 0, which means the function is concave down at all values of x.
For any such function, within the domain of a ≤ x ≤ b, the secant line S(x) is below the curve of f(x), and the tangent line T(x) is above the curve of f(x).
Here's an example:

All of the five statements are true expect for the second one (Points P and M are on plane B and plane S) and the fifth one (line d intersects plane A at point N).
The second statement is false point M does not lie on plane s, making the statement false. Also, line d intersects plane A at L, not n.
