Task: Answer the multiple-choice question.
Question: Which drug has a 4.549\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCCCn1c(N)c(N(CCOC)C(=O)CCCc2nc3ccccc3c(=O)[nH]2)c(=O)[nH]c1=O
b: C=CCn1c(O)c(/C(C)=N/N2CCCCCC2)c(=O)[nH]c1=O
c: Oc1ccc(O)c(Cc2nc3ccccc3[nH]2)c1
d: C[C@@H](NC(=O)C1(c2ccccc2)CCN(C(=O)OC(C)(C)C)CC1)C(=O)N[C@@H](Cc1ccccc1)C(=O)O
Answer: b. C=CCn1c(O)c(/C(C)=N/N2CCCCCC2)c(=O)[nH]c1=O
