1. B is incorrect; either you copied something wrong or your book is wrong.

2. A sounds very awkward.

3. B is the answer. It is better to replace "about" with "that".

4. A is the answer. It should read "constantly" (adverb modifying the word improving). C should not be "more effectively". Effectively is an adverb which has no place in that part of the sentence.
