d.
cad makes the process of designing complex and tedious.

B.   CAD produces designs that are of the highest quality.

C.   CAD provides systems for error-free manufacturing.

Explanation:

B.   CAD produces designs that are of the highest quality.

CAD does produce the highest quality of design, way better than what traditional paper plans can do.

C.   CAD provides systems for error-free manufacturing.

Many manufacturing systems can read CAD designs directly before the need of a human intervention in between, that eliminates possible errors.

Answers A and D are not true, because once passed the learning-curve, CAD greatly accelerates the production of designs.  And we know the learning-curve is behind them because the question says he has adopted the new system.

B CAD produces designs that are of the highest quality
