Step-by-step explanation:

From the image below, we have that

$arc\angle ACB=240^0$

Find,

$\angle B$

Arc angle

$arx\angle ABD=360-240=120^0$

From the image below, we will have the final answer to be

Hence,

Using the Alternate segment theorem,

$\angle B=60^0$

OPTION C is the correct answer
