Which example shows an effective division of work?

A. Susy, Hailey, and Ira each research their topic and take notes. Then, they share notes, and each student writes a draft. They read each other's work and discuss what will go into the final draft. They take turns proofreading.

B. Susy and Hailey have conflicting ideas about which direction their presentation should take. Ira says that he can see both sides. He suggests Susy and Hailey each write a draft, and he will choose the best one.

C. Susy is worried about her grade, so she offers to do the majority of the work. Hailey says she has a debate competition coming up, so she is happy with Susy's idea. Ira says he will email Susy the websites he finds.

D. Since Susy is good with grammar, she will proofread. Since Hailey has more free time after school, she will make the slide show. Ira is a fast reader, so he will take notes on the research.
