The speaker in the poem "The first lesson" is C. a parent.
The poem tells a story about a parent and his daughter in a pool or some other water, and the parent is teaching his kid how to swim. Of course, the whole poem is a metaphor - it's not really about swimming, but an important lesson that a parent has to teach his child about life itself.
