The correct answer is B. Chronological order
Explanation:
In writing, organizational methods refer to the way the content or information of a text is organized depending on the purpose of the author, the type of text and the content of it. Most common organizational methods include chronological order, the order of importance, cause and effect order, comparison-contrast and spatial order. In the case of chronological order, the information is organized according to time, which means the details in a text are arranged the order they happened usually from the oldest even to the most recent event.
This is the case of the passage presented in the question which deals with life of Jack Roosevelt Robinson, in which the author explains all the relevant events of his life including the year he was born (1919), when he moved to California (1920), when he left college (1941), when he played baseball for the Kansas City Monarch (1944), when he was assigned to play for the Dogers (1946), etc, which means the author organizes the events according to the year they occurred and therefore the organizational method is chronological or in chronological order.
