Task: Answer the multiple choice question.
Question: Which compound exhibits a 1.447\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a C1COCCO1.O=C(Nc1cccc2ccccc12)C(=O)C1C(=O)Nc2ccccc21
b O=C(CSc1nnc(-c2ccc(Br)cc2)o1)Nc1cccc2ccccc12
c Cc1cc(=O)cc(C)[nH]1
Answer: b. O=C(CSc1nnc(-c2ccc(Br)cc2)o1)Nc1cccc2ccccc12
