b. False

True

Explanation:

Binaries are a way of simply classifying or dividing objects into two sets or categories.we can understand this by the simple example of when we say we wish to divide something into two(just like we would we say we wish to divide something into three as in triple). In this case therefore there is usually two opposing sides with contrasting features.

Either/or categories are situations that present the need to choose between two alternatives as in a binary classification which disqualifies any object that doesn't fit sharply into any of these categories
