Task: Answer the multiple choice question.
Question: Which drug has a 5.642\% human ether-à-go-go related gene (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 Nn1c(SCC(=O)Nc2ccccc2F)nnc1-c1cccnc1
b COc1ccc(C2C(C#N)=C(N)N(c3sc4c(c3C#N)CCCC4)C3=C2C(=O)CC(C)(C)C3)cc1
c O=C(NCCN1C(=O)S/C(=C/c2cccnc2)C1=O)C1CC(=O)N(Cc2ccccc2)C1
d COc1ccc(OP(=O)(Nc2ccccc2)Nc2ccccc2)cc1
Answer: b. COc1ccc(C2C(C#N)=C(N)N(c3sc4c(c3C#N)CCCC4)C3=C2C(=O)CC(C)(C)C3)cc1
