… Tenisu wo shimasu.
What are you doing at Sunday ?
… I play tennis.
The answer is playing tennis which is indicating an activity. The correct answer will be ‘nani wo’ (なにを). It can be translated as ‘what is ‘. If it is combined with ‘shimasuka’ (しますか) means what do you do ?.
The answer ‘doko de’ (どこで) is asking about the location of the activity and the other answer ‘nan de’ (なんで) can be translated as means or way on doing something.
2. Kanji :
（どこへ、どこで、いつ）その カメラを かいましたか。
（どこへ、どこで、いつ）その カメラを かいましたか。
（doko e, doko de, itsu） sono kamera wo kaimashitaka.
… Oosaka depa-to de kaimashita.
Where did you buy that camera ?
… (I) bought it at Oosaka department store.
The correct answer is ‘doko de’ (どこで) which is asking the location of the place of the activity. It is a correct answer since the answer is also a location or a place, Oosaka department store where the activity is done which is buying a camera.
The other answer’s option is false ‘doko e’(どこへ) is actually translated as the place where the subject is heading to not doing the activity. The other option, ‘itsu’ (いつ) is actually used to ask when the activity is done or being done.

The other option is false. The answer ‘nan de’ (何で) is actually used to ask by what or what kind of means or way is used by doing the activity. It can be used if the answer is by hand, by fork, by spoon, etc.
The other option, ‘doko de’ is translated as ‘where’ and it is actually used to ask for the location or the place of the activity which is happened.
