Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -14.795\% 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 other words.
Options:
[a] O=C(CNC(=O)c1ccccc1)Nc1cccc(C(F)(F)F)c1
[b] O=C(OCC#CCSc1nnc(-c2ccncc2)o1)c1cccs1
[c] COc1ccc(CCNC(=O)Cn2nc([N+](=O)[O-])c(Br)c2C)cc1OC
[d] Cn1c(N)c(C(=O)COC(=O)CCC2CCCC2)c(=O)n(C)c1=O
[e] O=C(CCN1CCN(c2ccccn2)CC1)Nc1ccc(F)cc1
Answer: b. O=C(OCC#CCSc1nnc(-c2ccncc2)o1)c1cccs1
