Task: Answer the multiple choice question.
Question: Which compound has a 21.034\% 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(NCC(c1ccc(F)cc1)N1CCOCC1)c1ccccc1F
b.) COc1ccc(OC)c(C(=O)NC(CC(N)=O)c2ccc(N3CCN(c4ccccc4)CC3)c([N+](=O)[O-])c2)c1
c.) O=S(=O)(c1ccccc1F)N1CCN(c2nc(-c3cccnc3)nc3ccccc23)CC1
d.) O=C(CCNC(=O)c1ccc(Br)cc1)NCC(c1ccco1)N1CCCCC1
e.) CC1NC(=S)N(C2CCCCC2)C1=O
Answer: e. CC1NC(=S)N(C2CCCCC2)C1=O
