LaTeX Error: Unknown float option `q'

This error appears when a float option is used which LaTeX does not recognise. The float specifier is written in the square brackets whenever you use a float such as a figure or a table i.e. the h in \begin{figure}[h]. The only valid float specifiers you are able to use are h, t, b and p, with the addition of H if you include \usepackage{float} in our preamble. If you write a float specifier which LaTeX does not recognize in the square brackets, it will generate an error such as the one below.
