This is a reflexive verb, which means that the "se" must correspond with the subject. In this case the subject is "yo" which means that you must change "se" to "me"
You will then conjugate the verb normally (I am going to assume that you need it conjugated in the present. If not let me know)
Tomar which means to drink or to take in the yo form is tomo. Trabajar means to work, nadar means to swim, and practicar means to practice and it is saying I _ a soda, so the answer is tomo.
