c. to increase prussias power by unifying the german states
d. to contain frances power by surrounding it with strong states

Explanation:

The map shows post-Napoleonic Europe, aligned with the Congress of Vienna's goals. The key aim was to contain France's expansion by creating strong neighboring states: strengthening Piedmont-Sardinia, the Kingdom of the Two Sicilies, and solidifying Spain/Portugal as buffers, plus other adjustments to encircle France. Option A is incorrect as Switzerland remained landlocked. Option B is wrong because the focus here is not on Russia and the Netherlands. Option C is incorrect as German unification happened decades later, not at this time.

Answer:

D. to contain France's power by surrounding it with strong states
