or = か(ka)、もしくは(moshikuwa)、または(matawa)、それとも(soretomo)
"か、もしくは、または" are used for positive, negative and interrogative sentence.
"それとも" is used for just interrogative sentence.
We normally say "か" .
"もしくは, または, それとも" are a little formal.
Which do you want to go to Pizza hut or McDonalds?
= ピザハット(Pizza hut) か マクドナルド(McDonalds) どっちに いきたい ですか?
But, we sometimes say "ピザハット と マクドナルド どっちに いきたい ですか?".
と = and
They are same meaning in this case.
We say "これ ですか? それとも あれ ですか?" when we want to say "Is it this or that?".
Or we say nothing. "これ ですか? あれ ですか?"
By the way,
If you don't add "ですか" to the end of interrogative sentence, it becomes casual.
We don't add it when we talk with our family and friends .
Japanese is difficult... Haha
