The use of simulations has been limited by their a. inability to incorporate situations that a trainee might encounter b. inability to be used on a desktop computer c. need for employees to travel to a central training location d. high development costs

d

High development costs.

Explanation: Simulation is an approximate imitation of a process or a system that represents it overtime.

In Computer simulation is said to be a process of mathematical modelling that is performed on a computer and is designed to predict the behaviour of or the outcome of a physical system. Computer simulations are now useful tools for the mathematical modeling of many natural systems like in computational physics, astrophysics, climatology, chemistry, biology and manufacturing and also human systems like in economics, psychology, social science, health care and engineering.

" Simulations can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions and also to do a wide range of other things", but its development cost is very high, Very expensive.

D. High development costs

Explanation:

Simulations try to as much as possible imitate the functions or activities of a system or process. They cut across various disciplines such as education, technology, science, management and so on.

One common ground about simulations is that it accrues high development costs. This is due to its closeness to the real-world application. Each block of the real process has to be appropriately simulated to ensure that the same results are obtained.
