A Type Il error would be convicting an innocent person.

Explanation / Answer

Our null hypothesis is

H0: The defendant is guilty.

& alternate hypothesis is

H1: The defendant is not guilty.

We know that Type 1 error is Rejecting H0 when H0 is true and Type 2 error is Accepting H0 when H0 is false.

So here Type 1 error will be when we do not convict a guilty person and Type 2 error will be when convict an innocent person.

Hence option D is the correct option.
