Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.375\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. COCCNC(=O)c1ccc(CS(=O)(=O)c2cccc(C(F)(F)F)c2)o1
b. O=C(CSc1nc2c(cnn2-c2ccccc2)c(=O)[nH]1)N1CCOCC1
c. O=C(N/N=C/c1ccc(Cl)c([N+](=O)[O-])c1)c1cc(-c2ccc3c4c(cccc24)CC3)n[nH]1
Answer: b. O=C(CSc1nc2c(cnn2-c2ccccc2)c(=O)[nH]1)N1CCOCC1
