Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.942\% 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 additional words.
Options:
a COc1ccc(C(C)=O)cc1COC(=O)c1cc(C)nc2ccccc12
b Cc1c(CN2CCC(CO)(CC3CCCCO3)CC2)cnn1C
c CCOC(=O)c1c(C)[nH]c(C(=O)N2CCN(C(=O)OCC)CC2)c1C
d O=P(Nc1cccnc1)(Oc1ccccc1Cl)Oc1ccccc1Cl
Answer: a. COc1ccc(C(C)=O)cc1COC(=O)c1cc(C)nc2ccccc12
