Answer:
The correct answer is Él ve a la duquesa.
Explanation:
The important thing about this sentence is knowing how to locate the article.
Articles always accompany a noun with which they agree in gender (masculine, feminine) and number (singular, plural). In Spanish, there are two types of articles: indeterminate articles (un, una, unas, unas) and definite articles (el / los, la / las, lo).
The way in which this sentence would be correctly written would be:
Pronoun + verb + preposition + definite article + noun.
       Él         ve         a                   la                         duquesa.
