Answer:
B
Step-by-step explanation:
Larga and bonita are both in the feminine way, and pelo is masculine, so it can't be a. Rizada and ondulada both mean curly in spanish, so the sentence would not make sense if you plugged both of those words in for the missing blank. Also, for option D, onduladas is plural and nothing in the sentence is plural, so he only reasonable option is B.
Hope this helps :)
