Task: Answer the multiple choice question.
Question: Which compound has a -7.912\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 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=C1C2C3C=CC(C3)C2C(=O)N1c1ccc(Cc2ccncc2)cc1
b. O=C1CN=C(c2ccccc2)c2cc(Br)ccc2N1
c. Cc1ccc2nc3c(cc(C(=O)NCCc4ccccc4)c(=N)n3CCCN3CCOCC3)c(=O)n2c1
d. N#Cc1ccccc1NC(=O)c1ccccc1OCC(=O)Nc1ccc2c(c1)oc1ccccc12
e. C=CCn1c(SCC(=O)N2CCOCC2)nc(O)c(Cc2ccccc2)c1=O
Answer: b. O=C1CN=C(c2ccccc2)c2cc(Br)ccc2N1
