Let us consider two tangents AB and BC with centre at O.

We know that angle AOC and angle ABC are supplementary.

Now,


\begin{gathered} \angle AOC=360-226 \\ =134^o \end{gathered}

Now,


\begin{gathered} \angle AOC+\angle ABC=180 \\ 134+y=180 \\ y=46 \end{gathered}

Hence, the correct option is (A)
