in what way, if any, are total enterprise training systems and functional simulations related?

a)they are not related because they address completely different aspects of different fields.
b)they are essentially identical; they are two different ways of referring to the same thing.
c)they are both used to train people to excel in high-pressure military situations.
d)they are both used to train people in decision-making within the realm of business.

d)They are both used to train people in decision-making within the realm of business.

Explanation:

The total enterprise training Systems and the functional simulations address the same aspects of the different fields. And hence the first one is not the correct option. And they are identical in terms of usage only, and they are the same ways of referring to two different things, and different form of training. They have no connection with the high-pressure military situations as well. However, both of them are being used to train the people in the decision making inside the realm of the business. And hence the fourth or the D option is the correct one.
