Since n is a non-negative integer n can take 0,1,2,3,4,5

Greatest value in a fraction means n should be smallest i.e. 0
$$1/2^0$$ = 1

B

n is a non-negative integer = N is 0 and all positive integer

0<10n<1,000,000 means Power n can have max value as 5 which will give 100,000

and n can have minimum value as 0 which will make 10n = 1.

So n can be 0,1,2,3,4 and 5

So what value can be taken to make 1/2n (Power N)as max value. So minimum can be taken to make 1/2n max ..which is Zero can be taken.

So Answer will be 1/1 = 1 == Option (B)

$$0 < 10^n < 1,000,000$$

0 < 10^n < 10^6

So, n could be 0,1,2,3,4,5 since n is a non-negative integer.

The greatest value of $$\frac{1}{2^n}$$ could be achieved if 2^n is the smallest, i.e. for n = 0 at which the fraction becomes 1/2^0
or 1/1 = 1.

Ans B) 1
