Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.750\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CCNC(=O)/C(C#N)=C/c1c(N2CCOCC2)nc2ccccn2c1=O
(b) O=C1CSC(=S)N1c1cccnc1
(c) COc1ccc(C(=O)N/N=C/c2cc(Br)ccc2O)cc1OC
(d) CC(C)(C)OC(=O)N[C@@H](Cc1ccccc1)c1nnc(SCC(N)=O)o1
(e) Br.Cn1c(=N)n(CC(=O)c2ccc(Br)cc2)c2ccccc21
Answer: a. CCNC(=O)/C(C#N)=C/c1c(N2CCOCC2)nc2ccccn2c1=O
{#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}?
