Solution

The correct options are
A Prevents oxygenated and deoxygenated blood from mixing
B Allows highly efficient supply of oxygenated blood to all parts of the body
In four-chambered heart, the left half is completely separated from right half by septa. This prevents oxygenated and deoxygenated blood from mixing. This allows a highly efficient supply of oxygenated blood to all parts of the body. This is useful in animals that have high energy needs, such as birds and mammals.
