intentional citation
unintentional plagiarism
unintentional reference
intentional plagiarism

Explanation:

The correct answer is "A. intentional plagiarism". Plagiarizing is copying from someone else without being given the permission, or giving the author credit. If you do however give him credit everything will be legitimate and it will be considered to be a citation. 

faulty parallelism is a grammar construction where there is no balance in the parts of a sentence they have a similar meaning but the grammar structure is not equivalent.

the correct version of this faulty parallelism in the sentence is:

jefferson wrote the declaration of independence, and he was the nation's third president.

the problem with the first version is that the sentence:

"jefferson was both the writer of the declaration of independence"

presents jefferson as both a subject and an agent for the verb "write" because if he was "the writer" then the declaration of independence was written by him, besides that fact, the sentence presents a dependent clause.

while the second sentence:

he was the nation's third president.

presents a basic subject+verb+object structure

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in both sentences:

jefferson wrote the declaration of independence, and he was the nation third president.

it means that the hockey puck was traveling very fast.
