Identify the best explanation for the study described below:

People who listen to slow music before going to work in the morning were shown to make more rational decisions throughout the day than people who listened to more uptempo music. Further studies have shown that rational decision-making depends nearly exclusively on the ability to weigh more options before making a choice.

A
Slower music makes people calm, which keeps them from losing their temper at work and wasting time in arguments.
B
Slower music relaxes the brain, which allows people to listen more carefully to their advisers without interrupting.
C
People who listen to slower music at work have less need to be woken up in the morning by uptempo music and are generally better rested.
D
Slower music relaxes the brain, which allows people to weigh their options and make less impulsive decisions at work.
E
Uptempo music can lead to a calmer overall disposition, which allows people to consider their options more carefully before making decisions.
