Answer:
C- Uncertainty.
Step-by-step explanation:
Louise Driscoll's poem "Hold Fast Your Dreams" talks about being positive despite any bad circumstance. The poem basically reminds its readers to be hopeful and always never lose hope for their dreams.
The line "where doubt and fear are not" is taken from the first stanza of the poem. And the word "doubt" as used in the poem means uncertainty. The speaker advises to "keep one still, secret spot" in one's heart and where there is no uncertainty or fear.
Thus, the correct answer is option C.
