It is the 3rd one that definition is a great definition
This one is A- the sentence would be, “Accordinf to some studies, the children who touch the books physically before three years old are more LIKELY to have a good reading habit LATER in life.”
A. See
It's A because, "Right now I will see several porpoises swimming next to our boat." doesn't make any sense. Had seen and will have seen does not make sense, too. Hope this helped you! :)
