Answer:

Option c.

Step-by-step explanation:

We have the set of real numbers greater than 8 and B the set of real numbers greater than 5 here:

A: x+2>10 ⇒ x>8

B: 2x > 10 ⇒ x>5

8∉A ; 8∈B

Note: We can see (graph) that the intervals are open, so the corresponding points do not belong to their respective sets.
