Task: Answer the multiple choice question.
Query: Which compound has a 18.748\% 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.) CCCCC(=O)NC1(C(F)(F)F)NC(=O)N(C)C1=O
b.) Cc1cc(Cc2c(O)[nH]c(=S)[nH]c2=O)ccc1OC(C)C
c.) O=C(N=C1SC2CS(=O)(=O)CC2N1c1ccc(OC(F)(F)F)cc1)C1CC1
d.) Cc1ccc(N(CC(=O)NC2CCCCC2)C(=O)CNC(=O)c2ccco2)cc1C
Answer: a. CCCCC(=O)NC1(C(F)(F)F)NC(=O)N(C)C1=O
