Task: Answer the MCQ question.
Query: Which drug has a -22.189\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(O)C(=O)O.O=[N+]([O-])c1cccc(CN2CCN(Cc3ccc(Br)cc3)CC2)c1
(b) N#C/C(C(=O)N1CCOCC1)=C1/SC(Cc2ccccc2Cl)C(=O)N1c1ccccc1
(c) CC1=C(C(=O)OC2CCCCC2)C(c2ccccc2F)NC(=O)N1
(d) Cc1ccc(NCc2n[nH]c(=S)n2-c2cccc(Cl)c2)cc1
Answer: a. O=C(O)C(=O)O.O=[N+]([O-])c1cccc(CN2CCN(Cc3ccc(Br)cc3)CC2)c1
