Task: Answer the multiple choice question.
Question: Which drug has a -1.666\% 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 other words.
Options:
a CCOC(=O)C1=C(CC)Nc2ccccc2N=C1NC(=O)CCNC(C)=O
b COc1ccc(OC)c2[nH]c(=O)c(CCNS(=O)(=O)c3ccc(F)cc3)cc12
c C=CCc1cccc2cc(C(=O)OCC(=O)c3ccccc3)c(=O)oc12
d O=C(NCCc1ccccc1)c1nccc2ccccc12
e CC(C)c1ccc(/C=N/NC(=O)CC(=O)NC2CCCCC2)cc1
Answer: c. C=CCc1cccc2cc(C(=O)OCC(=O)c3ccccc3)c(=O)oc12
