Task: Answer the multiple choice question.
Question: Which drug has a -9.500\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) CSC1=NNC(c2ccc(C(C)(C)C)cc2)=NN1
b) CCc1nc(SCC(=O)NNC(=O)c2ccc(C)cc2)c2ccccc2n1
Answer: a. CSC1=NNC(c2ccc(C(C)(C)C)cc2)=NN1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
{#Question|Query!}: Which {#compound|drug!} {#has|exhibits!} a {herg_central_at_1uM#}{herg_central_at_1uM__units} {herg_central_at_1uM__names__noun}?
