Answer:

The method of ArrayList class which is used to obtain the present size of an object is:

a. size()

Explanation:

In ArrayList, the size() method provides the number of objects available in the collection, array, or list.  In Java programming, ArrayList forms a part of the collection framework and has a set of methods to access elements and modify them.  An ArrayList does not have a fixed-size data structure, unlike an Array, but continues to expand in size.
