C Correct answer
Explanation

Imperceptible means something so subtle or slight that it cannot be noticed or perceived by the senses or mind. The prefix 'im-' means 'not' and 'perceptible' means capable of being perceived. Improbable means unlikely, impregnable means unbreachable (usually fortifications), and intangible means abstract or unable to be touched.
