Task: Answer the MCQ question.
Question: Which compound has a -11.948\% 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: COc1ccc(C)cc1NC(=O)C(OC(=O)CNC(=O)c1cc(C)cc(C)c1)c1ccccc1
b: CCNC(=O)/C(C#N)=C/c1c(N(Cc2ccccc2)Cc2ccccc2)nc2ccccn2c1=O
c: Cc1cc(Br)cc(Cl)c1OC(=O)c1cnccn1
d: Br.O=C(CN1C2=NCCCN2c2ccccc21)c1ccc(Br)s1
e: O=C(O)/C(=C/c1cccnc1)NC(=O)c1ccccc1
Answer: b. CCNC(=O)/C(C#N)=C/c1c(N(Cc2ccccc2)Cc2ccccc2)nc2ccccn2c1=O
