Which sentence is punctuated correctly? our class is learning, about plant cells and reza’s class, is learning about animal cells. our class, is learning about plant cells and reza’s class, is learning about animal cells. our class is learning about plant cells and reza’s class is learning about animal cells. our class is learning about plant cells, and reza’s class is learning about animal cells.

The answer is the last option: Our class is learning about plant cells, and Reza’s class is learning about animal cells.

Explanation:

This question concerns the use of commas to punctuate correctly. The reasons why the first three sentences are incorrect are as follows:

1. They use commas to separate the subject and the verb:

- and Reza’s class, is learning about animal cells (sentence 1);

- Our class, is learning about plant cells and Reza’s class, is learning about animal cells (sentence 2).

2. They use a comma to separate the verb and the object for no apparent reason:

- Our class is learning, about plant cells (sentence 1).

3. They do not use a comma to separate two independent clauses connected by the coordinating conjunction "and":

-  Our class is learning about plant cells and Reza’s class is learning about animal cells.

That's why sentence 4 is the correct one. It properly uses a comma to separate the two independent clauses connected by "and". It does not separate subjects from verbs or verbs from their objects.

- Our class is learning about plant cells, and Reza’s class is learning about animal cells.
