Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.825\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C1CCC(c2ccccc2)(c2ccccc2)CC1
b O=C(CSc1nc2ccccc2n1Cc1ccc(Cl)cc1)N/N=C/c1ccc(C(=O)O)cc1
c CC(C)=NN1C(=O)c2ccccc2NC1(C)C
d CN(C)CCOc1ccc2ccccc2c1.O=C(O)C(=O)O
Answer: b. O=C(CSc1nc2ccccc2n1Cc1ccc(Cl)cc1)N/N=C/c1ccc(C(=O)O)cc1
