Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.480% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CCOC(=O)c1cnc(SCC(=O)Nc2ccccc2C(=O)OC)nc1N
b CCOC(=O)C(C(C)=O)C(c1ccc(OC)cc1)C(C(C)=O)C(=O)OCC
c O=C(CN1C(=O)/C(=C\c2cccc(Br)c2)Oc2ccccc21)NCC1CCCO1
d O=C(CCNS(=O)(=O)c1c(Cl)cccc1Cl)OCC(=O)c1ccccc1
e COc1ccc(CCCc2nnc(SCC(=O)Nc3nc(C)cs3)n2C)cc1C
Answer: c. O=C(CN1C(=O)/C(=C\c2cccc(Br)c2)Oc2ccccc21)NCC1CCCO1
