Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.487\% 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 other words.
Options:
a CCN1CCN(C(=O)COc2ccc(S(=O)(=O)N(C)Cc3ccccc3)cc2)CC1
b CCN(CC(=O)NC1CCCC1)S(=O)(=O)c1ccc(Br)cc1
c CC1=C/C(=C\c2ccc(Br)o2)C(=O)O1
d Cc1ccnc(NC(=O)c2cc(F)c(F)cc2Cl)n1
Answer: c. CC1=C/C(=C\c2ccc(Br)o2)C(=O)O1
