Average density of iron nail is greater than that of the water<br>3. Average density of the ship is less than that of the water<br>4. Average density of the ship is equal to that of the water<br>Select the correct answer using the code given below :
- A. 1 and 2
- B. 2 and 3 ✓
- C. 2 and 4
- D. 1 and 4
Correct Answer: B. 2 and 3
