Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.286\% 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, b, c, or d without using any other words.
Options:
a.) COc1ccc(N(CC(=O)N2CCN(C)CC2)S(=O)(=O)c2cc(C)ccc2OC)cc1Cl
b.) COCCNC(=O)/C(C#N)=C/C(C)=C/c1ccccc1
c.) CC(=O)Nc1cccc(NC(=O)COc2nncc3ccccc23)c1
d.) Cc1ccc2[nH]c(C)c(CC(=O)O)c2c1
Answer: b. COCCNC(=O)/C(C#N)=C/C(C)=C/c1ccccc1
{#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}?
