The correct Answer is:
To determine which of the statements A to D regarding frogs are correct, we will analyze each statement one by one. ### Step 1: Analyze Statement A **Statement A:** "Salivary glands are absent in frogs, so digestion starts in the stomach." - This statement is **correct**. Frogs do not have salivary glands, and as a result, the digestion of food begins in the stomach rather than in the mouth. ### Step 2: Analyze Statement B **Statement B:** "The skull of the frog is dicondylic." - This statement is also **correct**. The term "dicondylic" refers to the presence of two occipital condyles at the base of the skull, which is characteristic of frogs. ### Step 3: Analyze Statement C **Statement C:** "Frogs never drink water but absorb it through the skin." - This statement is **correct**. Frogs do not drink water in the traditional sense; instead, they absorb water through their skin, especially when they are in a moist environment. ### Step 4: Analyze Statement D **Statement D:** "Eyes of frogs exhibit binocular vision." - This statement is **incorrect**. While frogs have two eyes, they do not have true binocular vision like some other animals. Their eyes are positioned in such a way that they have a wide field of view, but they do not focus on a single object simultaneously. ### Conclusion Based on the analysis: - Statements A, B, and C are correct. - Statement D is incorrect. Thus, the option in which all the statements are correct is the one that includes A, B, and C.
