Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.451\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(c1ccccc1)c1cn(CC(=O)N2CCCC2)c2ccccc12
[b] Cc1ccc(C)c(NC(=O)CSc2nnc(-c3n[nH]c4ccccc34)o2)c1
[c] O=C1C(=O)c2c(C(=O)c3ccccc3)coc2-c2ccccc21
[d] CS(=O)(=O)N1CCC(Oc2ccccc2C(=O)NC2CCCCCC2)CC1
Answer: c. O=C1C(=O)c2c(C(=O)c3ccccc3)coc2-c2ccccc21
