We need to correctly match the items in List-I with their corresponding categories or examples in List-II. Let's analyze each item in List-I:
a. Pointing device:
A pointing device is an input interface that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. Among the options in List-II, a mouse (iv) is a classic example of a pointing device.
Match: a - iv
b. Output device:

Match: d - ii
Combining these matches, we get:
a - iv
b - iii
c - i
d - ii
This corresponds to option (3).
