user2274: Can some one tell me which is the best opening move when white plays e4, read somewhere, to counter e4 Sicilian Defence is one of the best?

user2042: Your question is unanswerable, please consider rephrasing it.
The reason for me saying this is that every opening that has = evaluation in ECO is good response to 1.e4. You could look for statistics on openings but it is useless-in my opinion statistics are stupid since they reveal to you nothing about the game. It is just a result of mathematical division-you can only use them to see which defense to 1.e4 is the easiest to play with for most of the people. 
Compare the French defense and Sicilian defense:
Currently Sicilian defense "scores better" than French defense according to statistics, but that conclusion is "valid" if you sum up the efficiency of all the variations in both openings.
If you remove the dubious Rubinstein variation of the French defense from the calculation than it scores nearly as good as the entire Sicilian defense.
My point is that you have many good opening moves against 1.e4, you just have to pick one you like.
Browse through openings against 1.e4and pick one that suites your style.
This depends entirely up to you-if you like slow games with small amount of variations to learn then pick some semi-open defense ( Caro-Kan, French-defense and so on ) or if you have time to learn and wish open battle riddled with sharp tactical play then pick Sicilian defense or Modern defense or whatever.
Remember: Each opening that is evaluated as valid, meaning it gives equal chances to both of you for winning is a good candidate.
You need to choose one that suits your style and just go with it.
If you have further question leave a comment.
Best regards.
