Answer: The correct options are

(B) +11

(C) -11.

Step-by-step explanation: We are given to select the numbers from the options that are 11 units from 0 on the number line.

We know that

the distance between a and b on the number line is given by

D=b-a, where b is greater than a.

So, we have

the distance between 0 and 0 on the number line is

$D=0-0=0~\textup{units}.$

The distance between +11 and 0 is

$D=+11-0=11~\textup{units}.$

The distance between -11 and 0 is

D=0-(-11)=11.

Thus, the required numbers that are 11 units from 0 are +11 and -11.

Options (B) and (C) are CORRECT.
