Task: Answer the multiple-choice question.
Query: Which compound has a 0.065\% 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 other words.
Options:
[a] O=C(OCCN=C1NS(=O)(=O)c2ccccc21)C1CC(=O)N(c2ccc3ccccc3c2)C1
[b] Cc1nc2ccccc2c(=O)n1/N=C/c1ccco1
[c] O=C(NN1CCCCC1)c1cccc2ccccc12
[d] O=C(O)C1C2C=CC(C2)C1C(=O)NC1CCS(=O)(=O)C1
Answer: a. O=C(OCCN=C1NS(=O)(=O)c2ccccc21)C1CC(=O)N(c2ccc3ccccc3c2)C1
