6 5 4 3 2 1

Explanation:

I do not now know which option it corresponds but the shape should look like above.

The logic is following;

There is a nested for loop. The inner loop prints the value of j, when j is smaller than or equal to i. Otherwise, it prints a space.

For example, in the first iteration i = 1 and j starts from 6.

i = 1, j = 6 -> print space

i = 1, j = 5 -> print space

i = 1, j = 4 -> print space

i = 1, j = 3 -> print space

i = 1, j = 2 -> print space

<u>i = 1, j = 1 -> print j</u>
