Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -7.662\% 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.) CC1CCc2cc(F)ccc2N1C(=O)CCC(=O)O
b.) CCOc1cccc(C=Nc2cc(C)cc(C)c2O)c1O
c.) C/C(=N\NC(=O)c1cccc(S(=O)(=O)N2CCOCC2)c1)c1ccc(O)cc1
d.) N#CC(C(=O)O)=C1CCCC1
e.) COc1ccc(C(C)=O)cc1CN1CCCCC1.Cl
Answer: d. N#CC(C(=O)O)=C1CCCC1
