Answer:
B. Telescope
Step-by-step explanation:
The earliest type of printing was called "wood-block printing", which was basically using blocks as stamps to "print" out words. The Chinese invented this around 650 AD.
The Chinese did not invent the first compass, but they did discover iron and its magnetic properties; they then improved on the compass by adding this component and producing the first magnetic compass.
Gunpowder's invention came around 620 AD during China's Tang dynasty; gunpowder and fireworks were actually invented in tandem with each other, I believe.
The only invention the Chinese cannot take credit for is the telescope. This was actually attributed to a Netherlands spectacle-maker named Hans Lippershey.
Thus, the answer is B.
Hope this helps!
