Task: Answer the multiple choice question.
Question: Which drug has a -3.045\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(/C=C/c1ccc([N+](=O)[O-])cc1)NCc1ccco1
[b] CCN1CCN(S(=O)(=O)Cc2ccccc2Cl)CC1
[c] COc1ccc(CCNC(=O)CC(=O)N/N=C/c2ccc(Br)cc2)cc1OC
[d] S=c1[nH]nc(-c2ccc(Cl)cc2Cl)n1-c1ccc2c(c1)OCCO2
[e] COc1ccc(NC(=O)CN(C)C(=O)/C=C/c2cn(-c3ccccc3)nc2-c2ccc(F)cc2)cc1
Answer: a. O=C(/C=C/c1ccc([N+](=O)[O-])cc1)NCc1ccco1
