Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.934\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(Nc1ccccn1)c1ccc(Cl)s1
b.) N#Cc1c(N)nc(SCC(=O)NC2CCCCC2)c(C#N)c1-c1ccc(Cl)cc1
c.) CCc1ccc2nc3nc(C)cc(C)c3c(N)c2c1
d.) Cn1c(/C(C#N)=C(\O)c2ccccc2Cl)nc2ccccc21
Answer: a. O=C(Nc1ccccn1)c1ccc(Cl)s1
