Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.900\% 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) CC1=C(C)CC2C(C1)C(=O)c1ccc(Br)cc1S2(=O)=O
(b) O=C(c1cc2c(s1)CCCC2)N1CCN(c2ccccc2)CC1
(c) Cc1ccn2c(C(=O)NNC(=O)Nc3ccc(Cl)cc3)c(C)nc2c1
(d) CC(C)(C)C(=O)N1CCN(c2ccnc3cc(Cl)ccc23)CC1
(e) O=c1[nH]c(C2CCN(S(=O)(=O)c3cccc(C(F)(F)F)c3)CC2)nc2c1nnn2Cc1cccc(F)c1
Answer: b. O=C(c1cc2c(s1)CCCC2)N1CCN(c2ccccc2)CC1
