Task: Answer the multiple-choice question.
Query: Which drug has a 9.753\% 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: CN(C)/C=C1/Oc2c(ccc3ccccc23)C1=O
b: O=C(c1ccc(Cn2cc(Br)cn2)o1)n1cccn1
c: COCCn1c(-c2cccs2)nc2nc3ccccc3nc21
d: O=C(N/N=C/c1ccc(Cl)cc1Cl)c1ccc(-n2cnnn2)cc1
e: Cc1ccc(SCCNS(=O)(=O)c2ccc(F)cc2)cc1
Answer: c. COCCn1c(-c2cccs2)nc2nc3ccccc3nc21
