Correct answer: A.
Reason: In the earliest moments the Universe was an extremely hot, dense soup of energy (radiation) and fundamental particles — mass and energy were interchangeable (E = mc^2). The usual idea that "everything came from a single point" is a simplified description of a state of extremely high energy density; energy itself need not be in the form of rigid matter occupying ordinary volume. (More precisely, the classical “singularity” is where our current theories break down; the Big Bang describes the rapid expansion of space itself rather than an explosion into preexisting space.)
