Question

[Question restatement] The prompt presents a set of consonant phonemes: [b], [z], [n], [r], [l]. The task is to identify which phonetic feature is being highlighted by these options.

Option 1: 'Voicing, place' — This mixes two features. 'Voicing' is indeed a shared property among the given sounds, but 'place' (where the tongue contacts the vocal tract) is not common to all of them since the group includes different places of articulation (bilabial, alveolar). This makes the pair inaccurate as a single shared feature.

Option 2: 'Place, manner' — Similar issue: the sounds differ in both place (bilabial for b, alveolar for z, n, r, l) and manner (stop for b, fricative for z, nasal for n, trill/approximant for r, lateral approximant for l). They do not share both place and manner, so this is incorrect as the sole common feature.

Option 3: 'Manner, place, voicing' — This suggests all three features are shared. However, the set includes sounds with stop, fricative, nasal, trill/approximant, and lateral approximant manners, and with varying places. So they do not share these three features simultaneously; this option overclaims commonality.

Option 4: 'Place' — This would claim all sounds share the same place of articulation, which is false: b is bilabial, while z, n, r, l are alveolar (and thus not all the same place).

Option 5: 'Manner' — This would claim a uniform manner across all sounds, but b is a stop, z is a fricative, n is a nasal, r and l are approximants/trills, so the manners are not identical.

Option 6: 'Voicing' — All listed sounds [b], [z], [n], [r], [l] are voiced in typical phonetic transcription: each sound involves vocal fold vibration. This makes 'voicing' the single feature that is common across the entire set, despite differences in place and manner.

In summary, the only feature that consistently applies to every item in the set [b], [z], [n], [r], [l] is voicing, because all these sounds are voiced phonemes, even though they differ in place and manner. The other options incorrectly claim shared place, shared manner, or both together, which does not hold for all items in the list.
