Question

Accepted Answer

# Explanation:
## Step1: Analyze lactose structure
Lactose is a disaccharide composed of galactose and glucose. Its formula is $C_{12}H_{22}O_{11}$, so it has 12 carbon and 11 oxygen atoms.
## Step2: Analyze sucrose structure
Sucrose is a disaccharide made up of glucose and fructose. Its formula is also $C_{12}H_{22}O_{11}$, having 12 carbon and 11 oxygen atoms. And it contains the monosaccharide fructose.
# Answer:
|  | lactose | sucrose |
|--|--|--|
| has 12 carbon and 11 oxygen atoms | Yes | Yes |
| is a disaccharide | Yes | Yes |
| contains the monosaccharide fructose | No | Yes |
