I also not agree with crown bevel gear because it is used in differential and the axis of differential is not more than 90 degrees.
I think the correct answer should be a internal bevel gear because when it connects the axis of the shaft angle is more than 90.

Pitch angle 90=corwn bevel gear.
Pitch angle <90 external bevel gear.
Pitch angle >90 internal bevel gear.
Pitch angle <90 external bevel gear.
Pitch angle >90 internal bevel gear.

In a pair of bevel gear, when one of gear has a pitch angle of 90 then it's called crown gear.

A crown gear (or a contrate gear) is a gear which has teeth that project at right angles to the face of the wheel. In particular, a crown gear is a type of bevel gear where the pitch cone angle is 90 degrees.
A pitch cone of any other angle is simply called a bevel gear. Crown gears normally mesh with other bevel gears, or sometimes spur gears.

Why bevel gear connect?

When the bevel gear connect two shafts whose axes intersect at right angle. Then they are called "mitre gears".
When the bevel gear connect two shafts whose axes intersect at angle other than a right angle. Then called "angular bevel gear".
When the teeth on the bevel gear are cut on the inside of the pitch cone then they called "internal bevel gear ".
