4. when sugar is exposed to heat, the first thing to occur is that the sugar a. caramelizes and turns to a deep brown color. b. melts into a thick syrup. c. changes color from clear to brown. d. takes on the texture of caramel.

Option B is the correct answer.

When sugar is exposed to heat, the first thing to occur is that the sugar melts into a thick syrup.

When sugar is put on a heat, and it reaches a temperature of 320 degree F or 160 degree C, the sugar starts to melt. The solid crystals of sugar begin to melt at this temperature. Sugar crystals join together to form a thick caramelized syrup. After more heating, it will change the color to light brown.
