Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 3.035\% 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] O=C(CCN1C(=O)/C(=C/c2ccc(F)cc2)SC1=S)NCCc1ccc(O)cc1
[b] S=C(NCCc1ccccc1)N1CCn2cccc2C1c1cccnc1
[c] CCS(=O)(=O)N1CCN(c2ccc(C(=O)N3CCOCC3)cc2[N+](=O)[O-])CC1
[d] COc1ccc(/C=C2\SC(=O)N(CCC(=O)N3CCCCC3)C2=O)cc1OC
Answer: b. S=C(NCCc1ccccc1)N1CCn2cccc2C1c1cccnc1
