The answer that seems to make the most sense is:
A. Explain an image
A legend or a key typically give information that allow something to make sense. Most commonly used in a map
Guessing the words you are comparing are "plain" and "plains" the correct answer is C. Homophone; the two words are pronounced the same but have different meanings and sometimes different spellings. Because <em>plain</em> and <em>plains</em> are words that sound alike; but they have different meanings as in "<em>plain</em> cream cheese" the word plain means to be pure while the word <em>plains</em> in the part "crossing the plains in Kansas" is referring to the extensive area of Kansas country; lastly they have slightly different spellings as plain and plain<em>s</em>.
Option A. Homograph is wrong because the correct definition is two words are written the same, not pronounced the same.
Option B. Homophone is wrong because the correct definition is two words are pronounced the same, not written the same.
Option D. Homograph is wrong because in this case they are written the same as the <em>bear </em>(the verb to carry) and the <em>bear </em>(the animal). But for <em>plain</em> and <em>plains</em> they are not identical as one has a <em>S.</em>
The sentence above with the use of the correct word becomes:
<span>Mr. Winston (B.) brought up the subject during the meeting; even though it made everybody uncomfortable to talk about it.
To bring up a topic means to make it open for discussion.
</span><span>
</span>
That. I doubt you want a long explanation, but I must give one, so, simply. woodpeckers are animals, which are referred to as it or that. Rude, huh?
Can you please expand on the question so i can answer accurately
