10. Designers use computer software to run __ on designs to reduce cost and development - A. Simulations B. Prototype testing C. Destructive Testing D. Lifetime testing

## Step 1<br />The question is asking about the type of testing that designers use computer software to run on designs to reduce cost and development time. The options provided are Simulations, Prototype testing, Destructive Testing, and Lifetime testing.<br /><br />## Step 2<br />Simulations are a type of testing where a model or system is run on a computer to predict its behavior under different conditions. This is a common practice in design to reduce cost and development time.<br /><br />## Step 3<br />Prototype testing, Destructive Testing, and Lifetime testing are also types of testing, but they are not typically run on a computer. Prototype testing involves creating a physical model of the design and testing it. Destructive testing involves testing the design to its breaking point to see how it performs. Lifetime testing involves testing the design over its expected lifespan to see how it performs.
