The end products of articulatory motor processes that represent physical sound realities are called

• A. Phoneme inventory
• B. Acoustic phonetics
• C. Phonetic variations, speech sounds, and allophonic variations
• D. Phonotactics

Answer: (C)

The end products of articulatory motor processes are the actual sounds we produce when speaking—the concrete phonetic realizations of speech, including context-driven variants. This is why the best choice lists phonetic variations, speech sounds, and allophonic variations: it covers the audible speech segments and the contextual, non-contrastive variants (allophones) that still reflect physical sound realities. In contrast, a phoneme inventory refers to abstract units, acoustic phonetics focuses on sound waves rather than production, and phonotactics deals with allowable sound sequences, not the produced sounds themselves.
