The correct option is D $18$

Say:
In the image, we can see two groups of cookies.

Ask:
$\bullet$ What do we need to find out?
Ans: We need to find out the total number of cookies baked.

$\bullet$ What operation do we use here?
Ans: Addition

$\bullet$ Which word in the question denotes that we have to add?
Ans: The phrase “in all” denotes that we have to add.

$\bullet$ How many cookies are there in the first group?
Ans: $8$

$\bullet$ How many cookies are there in the second group?
Ans: $10$

$\bullet$ How many cookies are baked in all? Look at the picture and count the total.
Ans: $8+10=18,$ so $18$ cookies are baked in all.

Hence, Option B is the correct answer.
