(1-1/2)*(1-1/3)*(1-1/4)*(1-1/5)*(1-1/6)*(1-1/7)*(1-1/8)*(1-1/9)*(1-1/10), first solve the brackets, we will get 1/2*2/3*3/4*4/5*5/6*6/7*7/8*8/9*9/10, cancel 2 in 1/2 and 2/3, cancel 3 in 2/3 and 3/4, cancel 4 in 3/4 and 4/5, cancel 5 in 4/5 and 5/6, cancel 6 in 5/6 and 6/7, cancel 7 in 6/7 and 7/8, cancel 8 in 7/8 and 8/9, cancel 9 in 8/9 and 9/10, now we will get 1/1*1/1*1/1*1/1*1/1*1/1*1/1*1/1*1/1*1/10, then multiply1*1*1*1*1*1*1*1*1*1/1*1*1*1*1*1*1*1*1*10, then we will get the answer as 1/10, so option C is correct.
