Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.235\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1ccc(CNC(=O)c2cc(S(=O)(=O)N3CCOCC3)cn2C)cc1
(b) O=C(O)CCC(=O)c1ccc2c(c1)OCCCO2
(c) N#Cc1ccc(OCC(=O)OCC(=O)Nc2sccc2C(N)=O)cc1
(d) Br.CCCCCCCCOC(=O)c1c(CSC(=N)N)n(C)c2cc(Br)c(OC(C)=O)cc12
(e) O=C1C=C(N2CCOCC2)CO1
Answer: d. Br.CCCCCCCCOC(=O)c1c(CSC(=N)N)n(C)c2cc(Br)c(OC(C)=O)cc12
