a)should use costly components
b)narrower tolerances result in better design and production quality
c)design should use standard components
d)external dimensions of components should be such that they can be assembled together

Answer 1

option b is correct answer

Answer 2

While the characteristics that are showcased in options B, C,& D are true, only option A is false, i.e., Its not the right attributes of a safe design.

Because the safety of a material depends on the maximum stress that it can withstand, and these high strength materials can either be costly or cheap.

So accordingly physical strength depends on its properties and is irrespective of its cost.

Hence option A is to be chosen
