Task: Answer the multiple choice question.
Question: Which drug has a 18.438\% 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 additional words.
Options:
a.) O=C(O)CC(c1ccc(F)cc1F)N1Cc2ccccc2C1=O
b.) CC(=O)Nc1ccc2nc(SCC(=O)N3CCOCC3)sc2c1
c.) COc1cc(C(=O)N/N=C2\CCS(=O)(=O)c3ccc(F)cc32)cc(OC)c1OC
d.) O=C(Nc1ccc(NC(=O)c2cc3ccccc3o2)cc1)c1ccco1
e.) NC(=O)NC(CC(=O)OCC(=O)NC(=O)NCc1ccco1)c1ccc(Cl)cc1
Answer: a. O=C(O)CC(c1ccc(F)cc1F)N1Cc2ccccc2C1=O
