Task: Answer the multiple choice question.
Query: Which drug has a 13.985\% 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] CCOc1ccc(-n2c(SCC(=O)N3CCC(C(=O)O)CC3)nc3ccccc3c2=O)cc1
[b] OCCNNC(=S)NC1CC2C=CC1C2
[c] Cc1ccc(Cc2cnc(NC(=O)C3=NCCN3)s2)cc1
[d] CC(C)c1ccc(OCC(=O)N(Cc2ccccc2)c2ccccn2)cc1
[e] CC(/C=C/c1ccco1)=N/NC(=O)Cc1cccs1
Answer: b. OCCNNC(=S)NC1CC2C=CC1C2
