  0.65 ≤ x ≤ 2.35

Step-by-step explanation:

The ± symbol is pronounced "plus or minus." Then 1.5 ± 0.85 means ...

  1.5 + 0.85 = 2.35   or   1.5 - 0.85 = 0.65

These are said to be the end points of a closed* interval, so the interval is ...

  0.65 ≤ x ≤ 2.35

This is graphed as solid dots at 0.65 and 2.35 and the number line shaded between those dots.

_____

* "closed" means the endpoints are included in the interval. An interval is "open" if the endpoint is not included. The inequality for that is written using the < symbol instead of the ≤ symbol.

the answer is b.
