Task: Answer the multiple-choice question.
Question: Which drug has a 1.571\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) O=c1[nH]cnc2c1sc(=S)n2-c1ccccc1
b.) CCOC(=O)N1CCN(C(=S)NC(=O)C2CCCC2)CC1
c.) COc1ccc(C2C3C(=O)N(Cc4ccccc4)C(=O)C3ON2c2ccccc2)c(OC)c1OC
d.) CN(CC(=O)NCC1CCCCC1)CC(=O)Nc1ccccc1Br
e.) COc1ccc(CCNC(=O)COC(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)cc1OC
