Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.549\% 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(N/N=C/c1c[nH]c2ccc(Br)cc12)C1CC1
b. Cc1c(Br)c(C(=O)N(C)C23CC4CC(CC(C4)C2)C3)nn1C
c. COC(=O)c1ccc(NC(=O)CSc2nc3cccnc3n2C)cc1
d. COCCCNC(=O)C(C)N1c2cccc3cccc(c23)S1(=O)=O
Answer: a. O=C(N/N=C/c1c[nH]c2ccc(Br)cc12)C1CC1
