Answer:

Option B) triple the height

Explanation:

The rest of the question is the container has a shape of the cylinder and the options to select the answer.

The options are:

A) triple the radius

B) triple the height

C) triple the diameter

D) triple the circumference

=========================================

the container has a shape of the cylinder

The volume of the cylinder is = π r² h

It is required to choose which option is suitable so change the dimensions so that the volume is tripled.

So, the volume will be V' = ( 3 π r² h )

Check the options:

A) triple the radius

The new radius = 3r

∴ V = π (3r)² h = 9 π r² h

B) triple the height

The new height = 3h

∴ V = π r² (3h) = 3 π r² h

So, it is no need to check the other options.

The answer is option B

Note: both of option C and D will lead to the same result of option A
