2023 NFHS Football Rules Question

[LeRoy]

Just reaching out to the group on a question on the test

This is one of the video questions: And i am confused or missed something about the video, also i am guessing you will have to see the video before answering so it might be a while.

51. During an onside kick attempt from K's 40-yard line, K32 blocks R7 at K's 49-yard line. The kick is rolling at K's 48-yard line and has not been touched at the time the block occurred. The onside kick is recovered by K at R's 46-yard line. What is the final result following any potential penalty enforcement?
A. No foul. K first and 10 on R's 46-yard line
B. Illegal block. K free kick from K's 30-yard line
C. Illegal block. K first and 10 on K's 39-yard line
D. Illegal block. K first and 10 on K's 44-yard line

All the answers have K keeping the ball? Got the ball with "DIRTY HANDS"

I do not think any of the answers are correct!!!

Rule 9 – Section 3
ART. 7 No member of the kicking team shall initiate contact to (Block) an opponent on a free kick until:
a. The legal kick has traveled 10 yards
b. The kicking team is eligible to recover a free-kicked ball, or
c. The receiving team imitates a block within the neutral zone.

Penalty: ART. 7 – Illegal Block – Live ball foul – 10 yards

So i think the correct answer would be

Illegal block. R first and 10 on K's 39-yard line

What am I missing here?? Thanks for the comments
