Task: Answer the MCQ question.
Question: Which compound has a 5.267\% 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 additional words.
Options:
a) COc1ccc(CCNC(=O)/C(C#N)=C/c2cccc(OCc3ccccc3)c2)cc1OC
b) CCNc1nc(Cl)nc(N(NC(C)=O)C(C)C)n1
c) O=C(NCC1CCCO1)c1ccc2c(=O)n(Cc3cccc(Br)c3)c(=S)[nH]c2c1
d) COCCn1c(SCC(=O)NC(=O)NCc2ccccc2)nc2ccccc2c1=O
Answer: a. COc1ccc(CCNC(=O)/C(C#N)=C/c2cccc(OCc3ccccc3)c2)cc1OC
