Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.778\% 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 O=C(CSc1ccc2c(c1)OCCO2)NCC1CCCO1
b CCOC(=O)Cc1nnc(NC(=O)CSc2nc3ccccc3[nH]2)s1
c CCOc1ccccc1NS(=O)(=O)c1ccc(-c2cnc(C3CC3)o2)cc1
d COc1cccc(OCC(=O)N(C)Cc2nc(-c3ccccc3)no2)c1
e O=C(Nc1ccn(CC(=O)N2CCN(c3ccccn3)CC2)c(=O)n1)OCc1ccccc1
Answer: b. CCOC(=O)Cc1nnc(NC(=O)CSc2nc3ccccc3[nH]2)s1
