Task: Answer the multiple choice question.
Question: Which compound exhibits a -11.827\% 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, or c without using any additional words.
Options:
a: O=C(N1CCOCC1)N(Cc1ccco1)CC1CCCO1
b: COc1ccc(/C=C/c2nnc(NC(=O)COc3ccc(C)cc3)s2)cc1
c: O=c1c2ccccc2ncn1-c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: a. O=C(N1CCOCC1)N(Cc1ccco1)CC1CCCO1
