Task: Answer the multiple-choice question.
Question: Which drug has a -2.416% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=[N+]([O-])c1cccc(-c2nnc(-c3ccc4c(c3)OCO4)o2)c1
b: CCn1cc(C2C(C(=O)Nc3ccc(Br)cn3)=C(C)NC3=C2C(=O)CCC3)c(C)n1
c: COCCN1CCN(Cc2cn[nH]c2-c2cc3ccccc3o2)CC1
d: COc1ccc(CCNC2=C(Cl)C(=O)N(CCc3ccc(OC)c(OC)c3)C2=O)cc1OC
Answer: a. O=[N+]([O-])c1cccc(-c2nnc(-c3ccc4c(c3)OCO4)o2)c1
