Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.155\% 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] C=CCN(c1ccccc1)S(=O)(=O)c1c(C)[nH]c(=O)[nH]c1=O
[b] COc1cc(C(=O)OCC(=O)Nc2ccc(F)cc2F)cc(OC)c1OC
[c] O=C1CCCCCC1C1(O)C(=O)Nc2ccccc21
[d] CSc1ccc(S(=O)(=O)N(CC(=O)NN=C2CCN(C)CC2)c2ccc(C)cc2)cc1
[e] Cc1ccc2[nH]c(=O)c3cc(C(=O)NCCC(C)C)sc3c2c1
Answer: c. O=C1CCCCCC1C1(O)C(=O)Nc2ccccc21
