Choose the correct bar graph according to the information given in the pictograph. If everyone gives $1$ jar to Tom, how many cookies does he have?

The correct option is B
Each cookie jar has $3$ cookies.
Number of cookies Max has $=5$ times $3=3+3+3+3+3=15$
Number of cookies Tom has $=3$ times $3=3+3+3=9$
Number of cookies Joy has $=4$ times $3=3+3+3+3=12$
Number of cookies Sam has $=6$ times $3=3+3+3+3+3+3=18$
The bar graph in Option B represents the same values.
If each of them gives $1$ jar to Tom, number of cookie jars Tom will have $=3+1+1+1=6$
Number of cookies Tom will have $=6$ times $3=3+3+3+3+3+3=18$
Hence, Tom will have $18$ cookies.
