Task: Answer the multiple-choice question.
Query: Which compound exhibits a -2.742\% 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.) O=C(NCCCn1ccnc1)c1cc(S(=O)(=O)N2CCOCC2)c(Cl)cc1Cl
b.) COc1ccc(/C(C#N)=C/c2c(-c3ccc(Cl)cc3)nc3c(C)cccn23)cc1
c.) COc1ccc(C2=C(C=O)Cc3ccccc3O2)cc1
d.) C#CCOc1c(Cl)cc(/C=C2/C(=O)ON=C2C)cc1OCC
e.) O=C(CCCc1ccccc1)NCCc1ccccc1
Answer: c. COc1ccc(C2=C(C=O)Cc3ccccc3O2)cc1
