Answer 2

Answer:

The correct options are 1, 3 and 6.

It is given that the H Is the circumcenter or a triangle DEF. It means H is the center of the circle that passes through the points D,E,F.

Option 1 is correct.

HD,HE and HF are radius of the circle,

$HE\cong HD$

Option 3 is correct.

$\angle DLH\cong FNH=90^{\circ}$

Option 6 is correct.

Therefore the correct options are 1, 3 and 6.
