Daisy Flower

I am not a researcher, for me it is very difficult to ascertain the scientific name of this flower. If I am wrong please forgive. Sagat many we find flowers like this. I've been searching from some source on the internet I was confused to find a scientific name about this flower, I finally decided with the name of daisy but I am not sure. The reason I am because this flower is very like daisy.
