Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.779\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) Nc1ccn(CC(=O)NCc2ccc3[nH]ccc3c2)c(=O)n1
(b) O=C(Nc1ccc2c(c1)OCO2)N1CCN(c2ncccn2)CC1
(c) CC(=O)n1cc(/C=N/NC(N)=S)c2ccccc21
(d) Cc1ccc(C)c(OCCC(=O)OCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)c1
(e) O=[N+]([O-])c1cc(C(F)(F)F)ccc1NN=C1CCCC1
Answer: b. O=C(Nc1ccc2c(c1)OCO2)N1CCN(c2ncccn2)CC1
