This or That (か)

か between two nouns means “or,” offering a choice the same way と means “and.” It attaches directly to both nouns with nothing else needed.

In Real Life
か only offers a choice between things, not a choice between actions. Choosing between two verbs needs 〜たり〜たりする or a different construction entirely, this か is strictly for nouns standing in for each other.
In Real Life
どちらか tacked on after the か pair spells out explicitly that a choice still needs to be made between them, “one of the two.” It’s not required, メールか電話をします already works fine, but どちらか makes the sentence read less like a vague list and more like a genuine either-or decision.
