The correct answer is letter B, Delta rays would have the same wavelength as most gamma rays.
Delta rays are by-products of secondary ionization of molecules. They have very low-penetrative power and are made-up of slow electrons and other particles that are a result of an ionizing radiation. When an ionizing radiation is present, it ejects atoms from a particle and the result is delta rays.

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.
