Task: Answer the multiple choice question.
Question: Which compound exhibits a 3.964\% 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) Cc1nn(-c2ccccc2)c(N2CCCC2)c1/C=N/NC(=O)C1CC1
(b) O=C(CCNC(=O)c1ccccc1Cl)NCCC1=CCCCC1
(c) Cc1ccc(CNC(=O)N2CCN(C)CC2)cc1
(d) COc1ccc2cc(C3=CCCCC3)ncc2c1
(e) CCC(C)(C)C1CCc2[nH]nc(C(=O)NCCNC(=O)OC(C)(C)C)c2C1
Answer: c. Cc1ccc(CNC(=O)N2CCN(C)CC2)cc1
