Lousy test question for fourth graders

My fourth-grade daughter is taking a series of standardized tests in school this week, called the ERB tests. Her teachers handed out a practice test last week, and when I was going over it, I came across a question in the math section that I think has several possible correct answers:

Picture 19-2
Sara wants to measure how much applesauce she made this fall. If she uses metric, which unit should she use?

A) gram

B) liter

C) kilogram

D) centimeter

I've shown this question to a movie director, a screenwriter, and a magazine editor, and they think its a lousy question, too. I've even heard a decent argument for d).
