The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Body Segments of Cockroach**: - The cockroach's body is divided into three main segments: head, thorax, and abdomen. 2. **Examine the Head Region**: - The head region contains important sensory organs. The primary sense organs in this region include the compound eyes and antennae. 3. **Analyze the Options Given**: - **Option A: Compound Eyes**: These are indeed sensory organs that allow the cockroach to see. They are made up of numerous small visual units called ommatidia. - **Option B: Johnston's Organ**: This is a group of sensory cells located at the base of the antennae, but it is not a complete sense organ. Therefore, it does not qualify as a sense organ in the same way as the compound eyes. - **Option C: Osphradium**: This is a sensory organ found in mollusks, not in cockroaches. It is related to the sense of smell. - **Option D: Spiracles**: These are openings for respiration in cockroaches and are not involved in sensory perception. 4. **Determine the Correct Answer**: - Based on the analysis, the only option that qualifies as a sense organ in cockroaches is **Option A: Compound Eyes**. ### Final Answer: The sense organs of cockroach include **compound eyes**. ---
