Hint: Some characters that differentiate bryophytes from algae are; bryophytes are mostly terrestrial while algae are mostly aquatic. Algae do not show division of labor among their cells and body part, but bryophytes show slight division of labor as they have leaf-like and stem-like structures.

Complete answer:
Option (A) Are thalloid forms – a thalloid, thalloid, or thalli form, refers to a plant structure resembling a thallus. The thallus is an undifferentiated vegetative tissue found in organisms like algae, fungi, liverworts, bryophytes etc. This character is found in both algae and bryophytes.
Option A is incorrect.
Option (B) Have no conducting tissue – Both algae and bryophytes have thalloid bodies with no conducting tissues. The conducting tissues were developed for the first time in pteridophytes. Thus, this option is incorrect.
Option B is incorrect.
Option (C) Possess archegonia – Archegonia is the female reproductive organ in bryophytes. These archegonia receive the male gametes through water current. It is not found in algae. Algae have a female reproductive organ called oogonia. This separates bryophytes from algae.
Option C is correct.
Option (D) Contain chloroplast – Chloroplasts are cell organelles which perform photosynthesis of photosynthetic organisms. It contains chlorophyll which captures sunlight and converts it into molecular energy; ATP and NADPH. Both algae and bryophytes are photosynthetic organisms, hence this option is incorrect.
Option D is incorrect.

Hence, Option (C) Possess archegonia is the correct answer.

Note:
There are certain characters that are similar in algae and bryophytes. Both these groups reserve carbohydrates as their source of energy. The early stages of gametophytes of bryophytes have green filaments which look exactly the same as the filamentous structure of the thallus of algae.
