Explanations:Understanding the concept of consonant blends and irregular spelling is crucial for mastering English orthography. Consonant blends, also known as consonant clusters, are groups of two or more consonants that appear together in a word and each retains its own sound. For example, in the word "black," the consonant blend "bl" consists of two distinct sounds, "b" and "l."
Irregularly-spelled words are those that do not follow the standard spelling rules of English. These words often have unique spellings that do not match their pronunciation, making them challenging to spell correctly. For instance, the word "choir" is pronounced as "kwahy-er" but is spelled with a "ch" blend, which is not typically pronounced as "kwahy."
When identifying irregularly-spelled words with consonant blends, it is important to consider both the pronunciation and the spelling of the word. In the given question, we need to find a set of words that contain consonant blends and are spelled in an irregular manner.
Let's analyze each option:
Option A: "Ache," "orchid," and "choir" are all words that contain consonant blends and are spelled irregularly. "Ache" has the blend "ch," which is pronounced as "k." "Orchid" has the blend "ch" and "id," where "ch" is pronounced as "k" and "id" as "id." "Choir" has the blend "ch" and "ir," where "ch" is pronounced as "kwahy" and "ir" as "er."
Option B: "Wash," "cash," and "brush" all contain consonant blends, but they are spelled regularly. The "sh" blend in these words is pronounced as "sh," which is a standard spelling rule.
Option C: "Play," "tray," and "clay" do not contain consonant blends and are spelled regularly. They follow the standard spelling rules for words ending in "ay."
Option D: This option is incorrect because there is a correct set of irregularly-spelled words with consonant blends in the given options, which is Option A.
Therefore, the correct answer is Option A: "Ache, orchid, choir." These words contain consonant blends and are spelled in an irregular manner, making them a good example of the concept being tested.
