Task: Answer the multiple choice question.
Query: Which compound exhibits a -5.429\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: C=C(C)CCC1(C)NC(=O)N(c2ccccc2)N1
b: O=C(NCCCn1ccnc1)C(=O)NCC(c1cccnc1)N1CCN(c2ccccc2)CC1
c: Clc1cccc(N/N=C/c2ccncc2)c1
Answer: a. C=C(C)CCC1(C)NC(=O)N(c2ccccc2)N1
