Task: Answer the multiple-choice question.
Question: Which drug has a -1.718\% 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 additional words.
Options:
a: CCN1C(=O)/C(=C/N(C)C)c2ccccc21
b: O=C(NCC1CCCO1)C1CCN(C2CCN(Cc3cccs3)CC2)CC1
c: O=C1/C(=C/c2cccs2)SC(=S)N1C1CCS(=O)(=O)C1
Answer: a. CCN1C(=O)/C(=C/N(C)C)c2ccccc21
