Complete the following collocation.

I was running late so I only had time for a _____ shower.

quick

The correct collocation to fill in the blank is quick shower.

The word "quick" means done or happening in a short time. It is the most appropriate option in this context because it conveys the idea that the shower was short and to the point.

The other options are incorrect.

• Hasty means done without care or attention. It does not make sense to say that the shower was hasty because the speaker was running late.
• Fast means done quickly. It is similar to "quick" but it is not as specific.
• Short can be used to describe a shower, but it is not as common as "quick".
