Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.924\% 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. CCCCOc1ccc(-c2nnc(-c3cc[n+](C)cc3)o2)cc1.O=S(=O)([O-])c1ccccc1
b. COC1=CCC2([N+](=O)[O-])CN(CCO)CC1([N+](=O)[O-])C2
c. COc1cccc(NC(=O)C(OC(=O)/C=C/c2ccc3c(c2)OCO3)c2ccccc2)c1
d. COc1ccc(NC(=S)NC(=O)c2cc3ccccc3o2)c(OC)c1
Answer: a. CCCCOc1ccc(-c2nnc(-c3cc[n+](C)cc3)o2)cc1.O=S(=O)([O-])c1ccccc1
