Best code to match corresponding list items?

Given two lists
A={a1,a2,a3,...}
B={b1,b2,b3...}

I want to produce the list
C={  {a1,b1}, {a2,b2}, {a3,b3}...}  }
as efficiently as possible.
Better yet, generalize to do this with N lists all of same length.

Obviously it can be done directly with Table, but is there a more elegant,
implicit way to write it that doesn't involve passing a function to Table
and using an explicit index? Is there a general functional primitive for
this that I simply haven't found? Seems like something so common, there
ought to be a built-in function for it.

Thanks,
Roger
