Answer 2

'There are three parts in the project', which clearly tells us that the fill in the blank should support plurals.

Now, the world plural denotes a greater quantity that is greater than one(it can be an object or people).

A plural subject must consist of  a plural verb. For example:

• They are laughing.

              Here, They is a plural subject, while are is a plural                                                          

              verb.

• The children are eating sandwiches.

              Here, The children is a plural subject, while are eating

              is a plural verb.

The right answer is:

Three parts of this project  are still unfinished.

Here, Three parts of this project is a plural subject while are is a plural verb.
