onto -
C.
a relation -
D.
a series
Correct Answer: Option B
Explanation
The function (y = g(x)) is one- to- one but (z = h(y)) is not one- to- one but onto.
(therefore h(g(x)) = onto)
(g circ h) is
The function (y = g(x)) is one- to- one but (z = h(y)) is not one- to- one but onto.
(therefore h(g(x)) = onto)
