Answer:
The correct answer that fills the blank is:
b) <u><em>Un guante</em></u>.
- <em>Los beisbolistas llevan </em><em><u>un guante</u></em><em> durante el juego.</em>
Explanation:
The translation of the sentence is:
- Baseball players wear <u>a glove</u> during the game.
While it is true that within a game there is a "hitter" that uses a baseball bat, the nine players of the opposing team that are inside the field use <u>a glove</u>, be it the pitcher, the catcher, a baseman (first, second or third) a short stop or a fielder (left, center or right), they all wear gloves during the game and are on the field until they get the batting turn.
