Problem statement: Answer the multiple-choice question.
Query: Which drug has a 1.770\% 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 other words.
Options:
a. O=C(c1cc(Br)c(Br)s1)N1CCN(c2ccccn2)CC1
b. Cc1ccc(C(=O)NCC(=O)NCCc2ccc(S(N)(=O)=O)cc2)s1
c. O=C(Cn1cc(/C=N/NC(=O)c2cccc3ccccc23)c2ccccc21)Nc1ccc(F)cc1
d. Cc1c2cnn(CC(=O)NCCN3CCOCC3)c(=O)c2c(C)n1Cc1ccc(F)cc1
Answer: c. O=C(Cn1cc(/C=N/NC(=O)c2cccc3ccccc23)c2ccccc21)Nc1ccc(F)cc1
