Some algae have chloroplasts and chlorophyll and obtain their energy through photosynthesis while some algae like euglena are both heterotrophic (decompose dead organic matter) and autotrophic (use photosynthesis) and can also obtain energy likewise.
In a hydra, digestion is completed intracellularly.
Hence option (a) is correct.
Small, freshwater organisms of the phylum Cnidaria and class Hydrozoa are grouped under the genus Hydra. They are indigenous to temperate and tropical climates.
The digestion takes place intracellularly in Hydra.
Because of their ability to regenerate and the fact that they don't appear to age or experience old age, hydra have drawn the attention of biologists.
Like most other cnidarians, hydras have a pretty straightforward digestive system.
They have a two-way digestive system, which differs from mammals in that food and waste enter and exit through the same aperture. A "blind gut" is the name for this configuration.
The center of the hydra's body is occupied by its digestive tract.

Inference is a process by which, through certain data, a conclusion is reached. Other synonyms for inference are conclusion, implication, ilation and consequence.
Accordingly, an inference is made when after watching a plant for a week, you determine that it needs more sunlight. This was a conclusion based on data.
Not all inferences offer true conclusions, even with data analysis. It is possible to state that all dogs are furry animals with four legs, but it cannot be inferred that all furry animals that have four legs are dogs.
Inferences usually arise from an analysis of characteristics and probabilities. If someone makes reference to an animal with four legs, hairy and wagging its tail, it can be inferred that the most certain thing is that it is referring to a dog.
