Task: Answer the multiple-choice question.
Question: Which drug has a 4.839\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(CSc1nc2nc(-c3cccs3)cc(C(F)(F)F)c2c(=O)[nH]1)NCc1ccco1
b. CCC(c1nnnn1CCOC)N(Cc1ccc(C)cc1)Cc1cc2cc(OC)ccc2[nH]c1=O
Answer: a. O=C(CSc1nc2nc(-c3cccs3)cc(C(F)(F)F)c2c(=O)[nH]1)NCc1ccco1
