Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.358\% 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) CCCS(=O)(=O)N1CCN(c2cc3c(cc2[N+](=O)[O-])n(C)c(=O)n3C)CC1
b) O=C(Cc1ccsc1)NCC(c1ccco1)N1CCCCC1
Answer: a. CCCS(=O)(=O)N1CCN(c2cc3c(cc2[N+](=O)[O-])n(C)c(=O)n3C)CC1
