Task: Answer the multiple-choice question.
Question: Which compound exhibits a -0.267\% 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) Cc1ncc(CO)c2cc(C(N)=O)c(=Nc3ccccc3)oc12
b) Cc1ccc(S(=O)(=O)NCCCN2CCCC2)cc1
c) O=C(N/N=C/C(Br)=C/c1ccccc1)c1cccnc1
d) Nc1ccccc1S(=O)(=O)c1ccccc1N
Answer: c. O=C(N/N=C/C(Br)=C/c1ccccc1)c1cccnc1
