Choose four sounds that are members of a natural class of English phonemes, and explain their shared features in square brackets.

1. /p/ [voiceless stops]

2. /t/ [voiceless stops]

3. /k/ [voiceless stops]

 /p/, /t/, /k/ are consonant sounds which have voiceless stops. These sounds are also aspirated at the beginning of words- i.e when pronounced, there is usually a forceful expulsion of air in words like "top", "tap", "kill", etc.

When the sounds are used at the end of words or joined with some consonants, they are not aspirated e.g drop, stop, etc.

4. /m/ [nasal stops]

When pronouncing nasal stops, the velum usually lowers to allow a free flow of air from the nose.

Examples of words that have nasal stops are:

"mouth", "mud", etc.

halibut, flounder, tuna, and trout are all fish. so your first answer is 1.) fish. and since fish is edible, your next answer would be 3). edible

to describe those fishes more thoroughly, some of those fishes live in fresh water, and some of the fishes live in salt water, and that is not a thing that they all have in common. the question is asking what is common with all of the fish, so answer choices 2). fresh water and 4). salt water are not right.
