Task: Answer the multiple choice question.
Question: Which drug has a 16.630\% 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 Fc1ccc(OCc2nnc(SCCN3CCOCC3)o2)cc1
b CCOC(=O)C(NC(C)=O)(Nc1ccc(S(=O)(=O)Nc2cc(C)on2)cc1)C(F)(F)F
c COCCNC(=O)c1ccc(C(=O)NCCOC)s1
d c1ccc(N2CCN(c3nc4ccccc4[nH]3)CC2)nc1
Answer: c. COCCNC(=O)c1ccc(C(=O)NCCOC)s1
