Kaijen this is really a good example of using punctuation. As in the question there is a semicolon and after that our intended part is getting started, we cannot use any connector or idiom (like All though, Even though or so) in front of it. So the only option left is A. Right? Hey Kaijen pls give a reply to ensure that u have understood!

here the subject is transpiration and so the verb shld be sing, which will eliminate C, D & E. In B we have even though connector but the structure of rest of the sentence does not match with even though connector... For even though it shld be like...even though X happened something opposite resulted..here we dont have such a structure in B...so remaining A is the ans.....Amitava ur reasoning is also right...Kudos man!!! u really rock...need ur help in the whole of SC part...can u pls reply to Brutal SC questions i've posted????

hello can some one please explain me the post of camitava
