Task: Answer the MCQ question.
Question: Which drug exhibits a 18.645\% 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 other words.
Options:
a COc1cccc(N2CCN(C(=O)CCSCc3ccccc3F)CC2)c1
b COc1cccc(CN(C(=O)Cn2nnc(-c3ccccc3F)n2)C(C(=O)NC(C)(C)C)c2ccncc2)c1
c COc1ccc(N2CC(O)=C(c3nc(-c4ccc(Br)cc4)cs3)C2=N)cc1
d Nc1c(C(=O)CSc2nncn2-c2ccccc2)c(=O)[nH]c(=O)n1C1CC1
Answer: c. COc1ccc(N2CC(O)=C(c3nc(-c4ccc(Br)cc4)cs3)C2=N)cc1
