Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.499% 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 other words.
Options:
[a] O=C(O)CCCC(=O)N1CC(=O)Nc2ccccc21
[b] COC(=O)c1c(NC(=O)c2ccc(C)cc2)csc1C
[c] CC(=O)N1CCCN(C(=O)c2cc(COc3c(F)cccc3F)on2)CC1
[d] CC(C)C[C@H](NC(=O)N1CC(=O)Nc2ccccc21)C(=O)N1CCC(C(=O)O)CC1
[e] Cc1cc(C(=O)N/N=C/c2cn[nH]c2-c2ccccc2)cs1
Answer: a. O=C(O)CCCC(=O)N1CC(=O)Nc2ccccc21
