The words sugar and carbohydrate are basically synonyms. Carbs can be broken down into glucose, galactose, fructose and mannose, which are called monosacharrides aka simple sugars. Sacharr is the Greek word for sugar. So I am not sure why you think you put down the wrong answer,

"Sugar" and "carbohydrate" are not synonyms (starch is a carbohydrate but not a sugar), but sugar is indeed a carbohydrate. I do not know why EngineerofScience thinks "carbohydrate" was a wrong answer on that quiz.

I said "basically". :)

Starch is a polysacharride, the Greek word for sugar is sacharr. Starch is made up of long-chains of glucose, and glucose is sugar. The body breaks down the polysacharrides it ingests down into simple sugars like glucose. So whatever the original form, it always ends up being sugar.

But yes, what you say is also correct. All sugars are carbohydrates, but not all carbohydrates are sugars (like starch for example, but even starch can be further broken down into sugars)...
