Answer:
The answer is A. a tissue
Explanation:
Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.
Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.
