Select the word that has the correct standard English spelling from the options given.

Introduction / Context:
This question tests basic spelling recognition in English. You are given four options that look like real English words, but only one matches the correct, standard spelling. Spelling questions like this are common in competitive exams because they quickly check whether a candidate has been exposed to accurate written English in reading and writing, and whether they can spot small but important errors in everyday vocabulary.

Given Data / Assumptions:

• We must select the correctly spelled word from: unweded, informmer, mongrels, powderred.
• Only one option follows accepted dictionary spelling.
• The likely intended real words are: unwedded, informer, mongrels, and powdered.
• No special technical or domain specific meanings are involved here.

Concept / Approach:
The strategy is to recognise the standard forms of common words and compare them with the given options. Examiners often introduce spelling traps by doubling or dropping consonants, or by inserting extra vowels. If you can recall seeing the correct form in books, newspapers, or reliable online sources, you can usually eliminate wrong variants. Here, mongrels is a common English noun referring to mixed breed dogs or animals, and it appears frequently enough in ordinary reading to be familiar.

Step-by-Step Solution:
Step 1: Think of unweded. The normal word for someone who is not married is unwedded, with double t in wedded. Unweded with a single d is incorrect. Step 2: Consider informmer. The correct noun from inform is informer with one m in the middle, not informmer with double m and extra letters. Step 3: Look at mongrels. This is the standard plural of mongrel, a mixed breed animal, and the spelling is exactly as used in dictionaries. Step 4: Examine powderred. The correct past participle of powder is powdered with a single r before e d, not powderred with double r. Step 5: Conclude that mongrels is the only option that matches a correct, established English spelling.

Verification / Alternative check:
If you place each option in a sentence, only mongrels looks right. For example, Many street dogs are mongrels is a perfectly natural sentence. By contrast, unweded bride, informmer to the police, or powderred sugar do not appear in standard texts and look visually wrong to experienced readers. If you consult a reliable dictionary, you will find mongrel and mongrels exactly in this form, which confirms the correctness of option mongrels.

Why Other Options Are Wrong:
Unweded is wrong because the base word is wedded, so the correctly spelled opposite is unwedded. Informmer is wrong because informer needs only one m. Powderred is wrong because the pattern is powder plus ed, giving powdered, not a double r spelling. These forms are not found in standard dictionaries and would be marked as errors in formal writing.

Common Pitfalls:
A frequent mistake is to overthink and assume that the less familiar looking word must be correct. Another pitfall is ignoring patterns in English word formation. For example, many verbs form past participles simply by adding ed without doubling consonants unless certain rules demand it. Building a habit of reading well edited material helps your eyes automatically recognise correct spellings. In time, the word mongrels will simply look right, while the others will immediately appear suspicious.

Final Answer:
The correctly spelled word is mongrels.
