Answer:
Direct
Step-by-step explanation:
Its direct characterization because Digory says " you behaved in a disgusting way" which tells a character's personality in a straightfoward, firm way and does not hint their actions or description.
Example:
Direct: Jace was a generous man.
Indirect: Jace helped the old lady cross the street.
Jace's action in the indirect sentence ONLY hints how he was generous. The direct sentence says it in a straightfoward, direct way.
I hope this sort of helps
