Task: Answer the multiple choice question.
Question: Which compound has a 11.379\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(CN1CCN(c2ccccn2)CC1)Nc1ccccc1
b. CCNC(=S)N(Cc1ccco1)Cc1cc2cc(OCC)ccc2[nH]c1=O
c. NC(=O)CC(NC(=O)c1ccc(Br)cc1)c1ccc(NCCc2ccc(F)cc2)c([N+](=O)[O-])c1
d. O=c1cc(N2CCN(Cc3ccccc3)CC2)[nH]c(=O)n1-c1ccc(Br)cc1
Answer: a. O=C(CN1CCN(c2ccccn2)CC1)Nc1ccccc1
