Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.429\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CC1(C(=O)NC(=S)N(CCC#N)c2ccccc2)CC1(Cl)Cl
b O=C(C1CCCN(Cc2cc(Br)ccc2O)C1)N1CCCCC1.O=C(O)C(=O)O
c COC(=O)C1=C(c2ccccc2)C[C@@H]2CC[C@H]1N2C(=O)NC1CC1
d O=C(Cc1cc(=O)oc2cc(O)ccc12)NCC1CCC(C(=O)O)CC1
Answer: a. CC1(C(=O)NC(=S)N(CCC#N)c2ccccc2)CC1(Cl)Cl
