Problem statement: Answer the multiple-choice question.
Query: Which drug has a 2.343\% 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. CCOC(=O)C1C(=O)NC(N2CCCCC2)=NC1C(C)C
b. O=[N+]([O-])c1ccc(CN2CCN(c3ccccc3)CC2)o1
c. Nc1nnc(CC(=O)N/N=C/c2ccc(-c3ccccc3)o2)s1
d. CCn1ncc(/C=N\NC(=O)c2csc3ccccc23)c1C
e. COc1ccc(C)cc1Nc1n[n+](-c2ccccc2)c(-c2ccc(OC)c(OC)c2OC)s1.[Cl-]
Answer: a. CCOC(=O)C1C(=O)NC(N2CCCCC2)=NC1C(C)C
