(b) 3″ order

(c) 1″ order

(d) 4″ order

This question was addressed to me during an online interview.

My question is taken from Classifications of Synthesis Problem topic in section Computer Aided Analysis and Synthesis of Mechanisms of Machine Dynamics

Answer 1

Correct answer is (c) 1″ order

To elaborate: As only one tangent is required to describe cubic spline, therefore its order is 1.
