Task: Answer the multiple choice question.
Question: Which drug has a 4.177\% 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: CC(C)N1CCC(NC(=O)Nc2ccc3c(c2)OCO3)CC1
b: CS(=O)(=O)Nc1ccc(C(=O)Nc2cccc([N+](=O)[O-])c2)cc1
c: O=C(CSC1=NCCS1)Nc1nc(-c2ccccc2)cs1
d: COC(=O)Cc1[nH]nc2c1C1(CCSCC1)C(C#N)=C(N)O2
Answer: c. O=C(CSC1=NCCS1)Nc1nc(-c2ccccc2)cs1
