OPtions are not provided in the question, The complete question is:

Some photosynthetic organisms contain chloroplasts that lack photosystem II, yet are able to survive. The best way to detect the lack of photosystem II in these organisms would be

A) to determine if they have thylakoids in the chloroplasts.

B) to test for liberation of O2 in the light.

C) to test for CO2 fixation in the dark.

D) to do experiments to generate an action spectrum.

E) to test for production of either sucrose or starch.

B) Test for liberation of O2 in the light.

Explanation:

Photosystem II is the first protein complex in the light-dependent oxygen photosynthesis reactions. It is found within algae, plant and cyanobacteria thylakoid membrane.

Enzymes absorb photons of light inside the photosystem to energise electrons, which are then transferred to plastoquinol through a combination of coenzymes and cofactors to minimise plastoquinone.

A test can be perform to liberate the oxygen (O2) in the light which is trapped in thylakoid membrane, if the light is liberated it shows presence of photosystem II and if no light will liberate, it shows lack of photosytem II.

Hence, the correct option is B.
