d. image

Explanation:

Step1: Define homoatomic and heteroatomic

Homoatomic molecules have only one type of atom; heteroatomic have more than one.

Step2: Analyze each model

• a: Molecule has two types of atoms (e.g., gray and blue) → heteroatomic.
• b: Molecule has one type of atom (red) → homoatomic.
• c: Molecule has two types of atoms (red and blue) → heteroatomic.
• d: Molecule has two types of atoms (gray and blue) → heteroatomic.

Answer:

a. Heteroatomic
b. Homoatomic
c. Heteroatomic
d. Heteroatomic
