Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.145\% 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 or b without using any other words.
Options:
a C=CCNC(=O)c1ccc2nc(Cc3ccc(OC)cc3)oc2c1
b CC1(C)CC(=O)C2=C(C1)N(c1ccc(Cl)cc1)C(=O)C2(O)C(F)(F)F
Answer: a. C=CCNC(=O)c1ccc2nc(Cc3ccc(OC)cc3)oc2c1
