The New Jersey Plan called for a Congress consisting of

Single house congress.

Explanation:

The New Jersey Plan is also known as Paterson plan or Small state plan and it is a proposal presented on the 15th of June, 1787 at the Constitutional Convention by William Paterson. William Paterson was the second governor of New Jersey and a co-signer of the Constitution of the United States of America.

Basically, the New Jersey Plan presented a proposed template (plan) for the structure of the government of the United States of America.

The New Jersey Plan called for a Congress consisting of a single (one) house congress i.e a unicameral legislature.

However, the New Jersey Plan was rejected at the Constitutional Convention while the Virginia Plan was adopted.

The Virginia Plan plan was drafted by James Madison in 1787 and it called for a legislature divided into two bodies (the Senate and the House of Representatives) with proportional representation in each state.

A bicameral legislative branch in which each state would be represented in proportion to their contribution or the number of people living in the state was proposed by The Virginia Plan.

Thus, States with large population would have more representatives in chambers than smaller states.
