Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.088\% 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) CS(=O)(=O)c1ccc2nc(NC(=O)CN3CCOCC3)sc2c1
(b) O=C1CC(Cc2ccccc2)C(=O)N1c1ccccn1
(c) Nc1nnnn1CC(=O)N/N=C/c1cc([N+](=O)[O-])ccc1Cl
(d) O=C(COc1ccccc1Cl)NCCCNC(=O)c1ccccn1
(e) O=C(/C=C/c1ccccc1[N+](=O)[O-])N1CCN(c2ccc(F)cc2)CC1
Answer: a. CS(=O)(=O)c1ccc2nc(NC(=O)CN3CCOCC3)sc2c1
