Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.484\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1cccc([C@@H]2CC=C(C(=O)O)[C@H](c3ccc(F)cc3)N2S(=O)(=O)c2ccc(C)cc2)c1
b O=C1CC(c2ccccc2)Cc2nc(NC3CC3)ncc21
c CCn1c(CNC(=O)c2ccccc2)nnc1SCC(=O)N1CCN(c2ccccc2)CC1
d CC(NS(=O)(=O)c1ccc2c(c1)C(C)(C)C(=O)N2C)c1ccccc1
Answer: b. O=C1CC(c2ccccc2)Cc2nc(NC3CC3)ncc21
