Not really but they are really cool and pretty
The answer is B. Encuentra. Because Encuenrta means To find and also matches with the Noun
a. en el café (in the coffee shop)
First of all, you'd knock b off the list because it states they are <em>going </em>to the coffee shop. They are obviously in. (en)
Second, café is masculine, so <em>el</em> would be chosen instead of la. (<em>la</em> is feminine)
And choice d doesn't even make sense...
Hope that helped :)
