The tables show the relationship between time, x, and plant growth, y, for two different plants. Which statements describe the relationship between x and y for the two different plants?

• Both plants show multiplicative relationships. For plant A, y is 2.5 times x, and in plant B, y is 3 times x.

• Both plants show additive relationships. For plant A, y is 2.5 more than x, and for plant B, y is 3 more than x.

• Plant A shows an additive relationship in which y is 2.5 more than x. Plant B shows a multiplicative relationship in which y is 3 times x.

• Plant A shows a multiplicative relationship in which y is 2.5 times x. Plant B shows an additive relationship in which y is 3 more than x.
