Task: Answer the multiple choice question.
Query: Which compound exhibits a -72.055\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(CN1CCN(C(=O)c2ccccc2)CC1)Nc1ccc(Br)cn1
b) C/C=C/c1ccc(OC)c(OC(C)=O)c1
c) Oc1ccc(Cl)c(Cl)c1
d) O=C(N/N=C/C(Br)=C/c1ccccc1)c1ccncc1
Answer: a. O=C(CN1CCN(C(=O)c2ccccc2)CC1)Nc1ccc(Br)cn1
