Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.447\% human ether-à-go-go related gene (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. CC(C)N(Cc1ccccc1)C(=S)Nc1ccc(OC(F)F)cc1
b. NS(=O)(=O)c1ccc(NC(=O)Cn2ncc3c2-c2ccccc2OC3)cc1
c. COc1cccc(N2CC(C(=O)Nc3nnc(SCCC4OCCO4)s3)CC2=O)c1
d. CC(C)(C)NC(=O)NC(=O)COC(=O)Cn1cnc2ccccc2c1=O
e. O=C(CCn1c(=S)oc2ccccc21)N1CCCCC1
Answer: a. CC(C)N(Cc1ccccc1)C(=S)Nc1ccc(OC(F)F)cc1
