Task: Answer the multiple choice question.
Query: Which drug has a 5.721% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a C/C(Nc1ccc(C)cc1)=C(/C#N)C(N)=O
b Cc1cc(C)c(Nc2cc(S(=O)(=O)[O-])c(N)c3c2C(=O)c2ccccc2C3=O)c(C)c1.[Na+]
c CC12CCC3c4ccc(O)cc4CCC3C1CC(O)C2O
d Clc1ccccc1OCCCCn1ccnc1
Answer: a. C/C(Nc1ccc(C)cc1)=C(/C#N)C(N)=O
