Tegmen is the inner layer of the seed coat.

Explanation:
The seed coat is built from the integuments that surround the ovule. The outer integument forms the outer portion of the seed coat, while the inner integument becomes the inner layer, known as the tegmen. So tegmen specifically refers to the inner protective layer of the seed coat. Endosperm and embryo are inside the seed, not part of the seed coat, and the outer layer of the seed coat is the outer integument (testa).
