Answer 1

The correct response is: **The indicator will change the color of the substance.**

In the case of starch, an iodine solution is commonly used as an indicator. When iodine comes into contact with starch, it produces a characteristic blue-black color. This color change indicates the presence of starch in the substance being tested.
