What type of information would be included in a phonological comparison between U.S. and British speech?

A phonological comparison focuses on the sounds of speech and how they are produced, which includes aspects like the articulation of consonants and vowels. In this context, the correct answer pertains to the place and manner of articulation of specific consonants. This means examining how sounds are physically produced in the vocal tract, which includes where the airflow is obstructed (the place of articulation) and how it is obstructed (the manner of articulation).

Differences in consonant sounds, such as those found in accents from the U.S. and British English—like the articulation of the ‘r’ sound in "car" or the 't' sounds in "water"—highlight how phonology varies between these dialects. Understanding these articulatory differences is crucial when analyzing phonological aspects of speech.

The other types of information mentioned, such as auxiliary verb placement, noun usage, and spelling variations, relate more to syntax, vocabulary, and orthography rather than phonology. While they are important in comparing languages and dialects, they do not directly address the phonetic and phonological characteristics that would be the primary focus of this kind of analysis.
