How much of a radioactive parent isotope remains after one half-life has passed?

all of the parent isotope because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay

half of the original amount because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay

one quarter of the original amount because half-life refers to the time it takes for half of a radioactive substance to undergo radioactive decay
