Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.882\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: C=CC[C@H]1Cc2c(cccc2[N+](=O)[O-])[C@H](CC=C)N1
b: Cc1oc2ccc(OS(C)(=O)=O)cc2c1C(=O)OC(C)C
Answer: a. C=CC[C@H]1Cc2c(cccc2[N+](=O)[O-])[C@H](CC=C)N1
