Answer 1

Answer: (A)

A, C and D only

There are three germ layers that occur in our body:

Ectoderm- the outermost layer

Mesoderm- the middle layer found between the ectoderm and the endoderm.

Endoderm- the innermost layer.

-Ectoderm is responsible for the formation of Epidermis which is the outermost layer.

-Mesoderm forms the dermis.

-Mesoderm also forms the skeletal muscles.

-The notochord is also formed by the mesoderm germ layer.

-Ectoderm is responsible for forming the enamel of teeth.

Therefore, A, C and D are the correct options,

Option B and E: Therefore, this is the incorrect option.
So, the correct option is A.
