Which component of physical education tests how much force an individual can put out all at once? muscular endurance flexibility body composition muscular strength

Muscular strength

in case you didn't know the definition of muscular strength, you could use process of elimination. it's not muscular endurance because endurance is testing how long you can do something over a period of time, and the question is asking about all at once. it's not flexibility or body composition because neither are testing how much force your body can exert. that leaves muscular strength.
