A hidden octave occurs when an implied consonant passing note would create a parallel octave. So in your example, the motion from A to D implies a consonant passing tone A-C-D, and of course C-D and C-D creates a parallel octave.

What are hidden octaves?
: an unsounded musical interval of an octave that is implied by the similar up or down motion of two voice parts and that if sounded would produce consecutive octaves.
What is a hidden octave in counterpoint?
So-called hidden consecutives, also called direct or covered octaves or fifths, occur when two independent parts approach a single perfect fifth or octave by similar motion instead of oblique or contrary motion. A single fifth or octave approached this way is sometimes called an exposed fifth or exposed octave.
What is a hidden fifth or octave?
Hidden fifths (hidden octaves are the same idea, but with octaves) is when two voices move in similar motion into a fifth in the next chord. This isn't the same as parallel fifths, where they move together from one fifth to another.
What is exposed 5th and 8ve?
Also known as “concealed” or “exposed” consecutives, these are a little harder to spot, but must be avoided. Hidden consecutives happen when: The bass and soprano parts form a perfect 5th or octave AND. The 5th/8ve is approached by similar motion AND. The soprano part is approached by a leap (not by step).
