10. A

11. C

 The correct option is (C). 0.78125.

Step-by-step explanation:  We are given to find the 10th term of the following geometric sequence

400,  200,  100, . . . .

We know that,

the n-th term of a geometric sequence with first term a and common ration r is given by

In the given sequence,

first term, a = 400

and

common ration is given by

Therefore, the 10th term of the sequence is

Thus, the correct option is (C). 0.78125.
