Answer is Wrong!
The correct answer is B. Reveal.
To conceal means to hide or keep something secret. To reveal means to make something known or visible.
A. Unfold means to open or spread out something that is folded or rolled up.
C. Open means to make or become open.
D. Discover means to find something that was previously unknown or hidden.
