Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.937\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1cc(CN2CCN(c3ncccn3)CC2)cc(OC)c1
(b) COc1ccc(Cl)cc1NC(=O)CN(C)C(=O)CCNC(=O)c1ccccc1OC
(c) N=C1C(c2ccccc2)=C(O)CN1c1cccc(O)c1
(d) COC(=O)c1oc2ccccc2c1NC(=O)c1ccccc1O
(e) O=C1C2ON(c3ccccc3)C(c3cccnc3)C2C(=O)N1Cc1ccccc1
Answer: c. N=C1C(c2ccccc2)=C(O)CN1c1cccc(O)c1
{#Task|Problem statement!}: Answer the {#multiple choice|multiple-choice|MCQ!} question.
