The pair is known as a higher pair, when the relative motion between the elements of a pair is

A turning only
B sliding only
C rolling only
D partly turning and partly sliding

Correct Answer: partly turning and partly sliding

When the two elements of a pair have a line or point contact when relative motion takes place and the motion between the two elements is partly turning and partly sliding, then the pair is known as higher pair.
