Which line use makes technical drawing more reliable?

Answer and explanation

Correct answer: Accurate straight and controlled lines

Answer: A. Technical drawing communicates measurable structure, shape, position, and boundaries. It must therefore use lines that are accurate, deliberate, and controlled. Straight edges, consistent thickness where required, careful angles, and clean joins help another person read or use the drawing correctly. Option A is correct because it supports precision and reliable information. Option B is wrong because trembling expressive lines can make an edge uncertain and may change the intended measurement. Option C is wrong because cloud-like lines are decorative or soft and do not normally define exact technical boundaries. Option D is wrong because scattered irregular lines create confusion about the actual shape or limit. A technical drawing may use different line types for different purposes, but every type is applied according to a rule. Memory cue: technical work needs control before decoration.
