Task: Answer the multiple choice question.
Query: Which drug exhibits a 10.872\% 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 or b without using any additional words.
Options:
[a] O=C(CNC(=O)c1cccs1)N/N=C/c1ccc(O)cc1O
[b] O=C1C(Cl)=C(N2CCOCC2)C(=O)N1c1cccc(C(F)(F)F)c1
Answer: b. O=C1C(Cl)=C(N2CCOCC2)C(=O)N1c1cccc(C(F)(F)F)c1
{#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}?
Constraint: You must select none, one or more options from {%multiple_choice_enum%2-5%aA1} without using any {#other|additional!} words.
