Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 14.677% 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] CCS(=O)(=O)Nc1cccc(-c2ccc3nnc(-c4cccnc4)n3n2)c1
[b] CCOc1ccc(NC(=O)C2CCCN(S(=O)(=O)c3ccc(-n4cnnn4)cc3)C2)cc1
[c] O=C(COc1ccc(Br)cc1)NCCO
[d] CCn1c(SCC(=O)NC2CCCC2)nnc1-c1ccccn1
[e] c1ccc(-c2cc(CSc3nc4ccccc4[nH]3)on2)cc1
Answer: c. O=C(COc1ccc(Br)cc1)NCCO
