Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.159\% 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 additional words.

[a] Cc1cc(C(=O)CN2c3cccc4cccc(c34)S2(=O)=O)c(C)n1C
[b] CCCCC(=O)Nc1ccc2c(c1)nc(CCN1CCN(C)CC1)n2C
[c] COC(=O)C1=C(O)/C(=C\c2ccc(OCC(=O)Nc3ccccc3OC)cc2)N=C1C
[d] S=C(NCCc1ccccc1)NC1CC1
Answer: d. S=C(NCCc1ccccc1)NC1CC1
