Explanation:

- "adolescence": This is the correctly spelled word. Adolescence refers to the transitional phase of growth and development between childhood and adulthood.

- "adolesense": This is an incorrect spelling. The erroneous use of 's' where 'c' is correct makes it misspelled.

- "adolescense": This is another incorrect variant. It has an extra 's' in place of the 'c'.

- "adolescance": Also spelled incorrectly. It incorrectly uses 'a' instead of 'e' in the suffix.
