Explanation:

The first Selma voting rights march (Bloody Sunday) on March 7, 1965, involved marchers being attacked by police (including state troopers) with tear gas, clubs, etc., as they crossed the Edmund Pettus Bridge. The first option is incorrect (police attacked protesters, not vice versa). The third option is incorrect (the number arrested was not 25,000 in the first march). The fourth option is incorrect (voting rights were achieved later, not during this first march).

Answer:

B. marchers were attacked by police as they crossed a bridge.
