Correct Usage of Adjectives with "Hair"
Step 1: Understanding the Rule
The noun "hair" is uncountable, so it does not take a plural form like "hairs."
The correct structure for adjectives is: adjective + adjective + noun.
Step 2: Choosing the Correct Phrase
The correct phrase is:
"long and black hair".
Step 3: Eliminating Incorrect Options
- "Longest and black hairs" (Option B): Incorrect because "hairs" should be "hair" and "longest" should be "long".
- "Blackening hair" (Option C): Incorrect because "blackening" is the wrong form.
- "Long and heavier hair" (Option D): Incorrect because adjectives should match in form (the correct form would be "long and heavy hair").
Step 4: Correct Usage
The correct sentence should be:
"She has long and black hair."
Final Answer:
Thus, the correct answer is Option A ("long and black hair").
