Task: Answer the multiple-choice question.
Query: Which drug has a -10.868% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(c1ccccc1)c1coc2ccc(O)c(Cl)c12
b.) O=C(CCn1c2c(c3ccccc31)CCCC2)NNC(=O)c1ccccc1[N+](=O)[O-]
c.) COc1ccccc1NC(=O)CSc1nnc(CNC(=O)c2ccco2)o1
Answer: a. O=C(c1ccccc1)c1coc2ccc(O)c(Cl)c12
