Final answer:
In the given molecule, there are eight chiral centers. The chiral carbons are a) C1 and C3.
Step-by-step explanation:
A chiral center is a carbon atom that has four different groups or atoms attached to it. In the given molecule, there are eight chiral centers. To identify each asymmetric carbon atom, we need to determine which carbons have four unique substituents. By examining the molecule, we can see that C1 and C3, C2 and C4, C5 and C7, and C6 and C8 are the carbons with four different groups attached to them. Therefore, the correct answer is (a) C1 and C3, as these carbons are chiral.
