Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 11.066\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a Cc1cccc(-n2[nH]c(C)c(C=Nc3ccc4[nH]c(=O)[nH]c4c3)c2=O)c1
b O=C1NC(=S)N(c2ccc(Br)cc2)C(=O)/C1=C/N1CCN(C(=O)c2ccco2)CC1
Answer: b. O=C1NC(=S)N(c2ccc(Br)cc2)C(=O)/C1=C/N1CCN(C(=O)c2ccco2)CC1
