Statements:
1. Some bananas are green.
2. Some green are yellow.

Conclusions:
I. Some bananas are yellow.
II. Some yellow are bananas
III. All yellow are bananas.
IV. Some green are bananas.

The basic diagram from the given statements is

I. Some bananas are yellow

From the basic diagram, some bananas are not yellow. Hence conclusion I do not follow.

II. Some yellow are bananas

From the basic diagram, some yellow are not bananas. Hence conclusion II do not follow.

III. All yellow are bananas

From the basic diagram, all yellow are not bananas. Hence conclusion III do not follow.

IV. Some green are bananas

From the basic diagram, some green are bananas. Hence conclusion IV follows .

$$\therefore\ $$Only conclusion IV follows the given statements

Hence, the correct answer is Option D
