Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.986\% 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 additional words.
Options:
(a) O=c1cc(Cn2ccnc2)c2cc3c(cc2o1)CCC3
(b) COc1ccc(CCNC(=O)CN(c2ccccc2OC)S(C)(=O)=O)cc1
(c) CCCc1ccc(C(=O)O/N=C(\N)c2ccccn2)cc1
(d) CC1Cc2ccccc2N1C(=O)COC(=O)c1ccc(N(C)C)cc1
(e) COC(=O)c1ccc(Oc2coc3cc(OCc4ccc([N+](=O)[O-])cc4)ccc3c2=O)cc1
Answer: a. O=c1cc(Cn2ccnc2)c2cc3c(cc2o1)CCC3
