Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.516\% 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, or c without using any additional words.
Options:
a) O=C(NN1CCOCC1)c1cn(-c2ccccc2)nc1-c1cccs1
b) CCOC(=O)[C@@H]1[C@H]2COc3ccccc3[C@@H]2N2C(=O)N(c3ccccc3)C(=O)[C@@]12C
c) Cc1nc(Oc2ccc(S(=O)(=O)N3CCOCC3)cc2Cl)c2c3c(sc2n1)CCCC3
Answer: a. O=C(NN1CCOCC1)c1cn(-c2ccccc2)nc1-c1cccs1
