The key to finding the correct descriptor of Yolanda is to pay attention to gender. Yolanda is a feminine name, thus the adjective used to describe someone named Yolanda (presumably a female) in Spanish would take a feminine form.
The options
A. reservado - reserved ~masc. singular
B. impaciente - impatient ~neither feminine nor masculine; singular
C. trabajador - worker ~masc. singular
D. simpático - nice ~masc. singular
Only one of these adjectives is neutral, while all others contain masculine conjugations. Our correct answer is clear.
Answer:
B. impaciente
