Instead of buying your child the latest electronic innovation this year for christmas or his or her birthday, why not try buying a more interactive and educational toy? studies have shown that children are increasingly turning to screens for amusement in a greater number of hours every year. this screen addiction is, in turn, lowering reading and math scores across the nation. i propose that this year you consider buying your child something technological, but not screen-oriented--like a telescope, magnifying glass, electronic circuit board, or microscope. it does not have to be a “real” scientific tool, but just one sophisticated enough to keep them interested.

which sentence would be the best concluding sentence for this paragraph?

a) whatever gifts you buy your child, it is important to note that it's not really the gift, but the thought that counts.
b) i think a telescope might be the best present for a child because as a child i was particularly fascinated by the stars.
c) i'm not saying that electronic screens are all evil, but they do seem to be having a bad effect on students' ability to learn.
d) not only will you be getting your child away from tyrannical screens, you may also be starting them off on an exciting future career!
