Elisabeth Stokes · Answer 1

Option (A)

Explanation:

The use of the word "although" is a subordinate conjunction that makes the whole first part of the sentence a subordinate clause.

The second part of the sentence provides an added role of the ice particles while the last part of the sentence gives the demerit of these ice particles. The whole sentence depends on the independent clause which is the last part of the sentence.

So, the form of the sentence is correct with the middle part adding an extra detail of the subject, while also completing the meaning of the whole sentence. The sentence needs no change.

Thus, the correct answer is option (A).
