Yet, a 2x2 game with a weekly dominated strategy might have two pure-strategy NE and zero mixed-strategy NE, because the oddity condition does not hold? So, the answer to my question (where I assume 1 NE, and so it seems I am imposing a strongly dominated strategy) is "yes, because of the proof of oddity of NE in strongly-dominated strategy". However, since player 1 will only play c regardless of whatever player 2 chooses, we can delete the a,b and d rows from the matrix.
