Explanation

The question asks for the capacity of a container. This sounds like it might be a geometry question, but glancing at the data statements, we can see that they don't give us dimensions of the container, but rather proportional information about its volume. Let's go to the statements, evaluating them separately first.

Statement (1) tells us that the container currently holds 12 liters of fluid. The (total) capacity of the container could be 12 and it could be full; or, in another allowed case, the capacity could be greater and the container could be partly full. If we knew how full 12 liters was, we could infer the capacity, but we don't have that info. So Statement (1) is insufficient.

Statement (2) tells us, if we consider the capacity in liters C, that



On the right side, the "amount of water in the bucket" is , and it increases by , so it scales by . We have a single linear equation with one variable, so we'll be able to solve for C. Statement (2) is sufficient.

The correct answer is (B).
