Task: Answer the multiple choice question.
Question: Which drug has a 19.788\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCNC(=O)CN(C1CCCCC1)S(C)(=O)=O
(b) O=C(Oc1ccc2ccccc2c1Br)N1CCCCCC1
Answer: a. CCCNC(=O)CN(C1CCCCC1)S(C)(=O)=O
