These types of questions contain grammatical errors in the underlined sentence, and we have to choose the correct statement from the options. GMAT sentence correction is part of GMAT verbal.

Answer: B
Explanation:

The following ideas could be used to back up the suggested alteration to the sentence:

• Parallelism
• Considering two distinct facts
• Modifiers

This is how the sentence is put together:

The 3.2 inch high resolution multi-touch display on the iPhone 4.0 is made of glass. Which is primarily a mixture of metallic oxides, as opposed to the 3.8 inch screen on the Nokia N8. And the 4.0 inch AMOLED dual touch capacitive display on the HTC Touch Pro, both of which are composed of organic compounds.

Let’s check the options one by one -

Option A is incorrect:
Choice A is incorrect. Here the sentence uses the word “both of which," so there has to be an end to the sentence.

Option B is correct:
Option B is the correct choice. It is written in passive voice, and it perfectly portrays the individual features of each of the given phones.

Choice C is incorrect:
Option C is incorrect. Here the sentence has used the phrase “each of which” so there has to be the end of the sentence. But it continues after the comma.

Choice D is incorrect:
In terms of parallelism or comparison, D is utterly flawed. The word that comes after "unlike," such as "unlike x," should be a noun.

Choice E is incorrect:
This is the incorrect choice. In terms of parallelism or comparison, E is utterly flawed. The word that comes after "unlike," such as "unlike x," should be a noun.
