Current Question (ID: 11792)

Question:

Identify the correct match: a. Felis: Canidae b. Datura: Solanaceae c. Petunia: Leguminaceae d. Dogs: Felidae

Options:

1. a. Felis: Canidae
2. b. Datura: Solanaceae
3. c. Petunia: Leguminaceae
4. d. Dogs: Felidae

Solution:

Datura is a genus of flowering plants in the family Solanaceae. Solanaceae is a family of flowering plants that includes various genera such as Solanum, Datura, Nicotiana, and others. Therefore, option b, Datura: Solanaceae, is the correct match. Option a is incorrect as Felis belongs to the family Felidae, not Canidae. Option c is incorrect as Petunia belongs to the family Solanaceae, not Leguminosae. Option d is incorrect as Dogs belong to the family Canidae, not Felidae.
