Q 3 Getting Started with Salesforce and Lightning Experience

Hi, I have a question regarding quesiton 3 in unit: "Getting Started with Salesforce and Lightning Experience unit"
3 Salesforce Lightning Experience:
A Is available only on mobile devices.
B Is optimized with flexible, interactive tools that sales reps can use to visualize data on the fly.
C Never strikes in the same place twice.
D Is optimized to be a fast and lightweight tool for your sales reps.

I understand the correct answer is B. but what is wrong with D?
Salesforce document says that 'Lightning Experience is the name for the all new Salesforce desktop app, with over 25 new features, built with a modern user interface and optimized for speed.'
Doesn't this mean that it is optimized to be a fast tool? My understanding is that lighting means fast hence speed is important.
To me answser B emphasizes on visualization and answer D emphasizes on speed. 
Why B is correct?

Thanks in advance.

Hi Ming,
I think that the word 'lightweight' is one thing that makes D wrong. Besides, Lightning Experience is made up of many tools and therefore is not only 1 tool as stated in D. That is my understanding of B being the right answer instead of D, but I could be wrong. have a good one.
