Option D is the correct choice because all the given relations are accurate. Option A correctly equates 1 Weber per square meter to N m^-1 A^-1, which is another expression for Tesla. Option B is correct as 1 Tesla equals 10,000 Gauss, bridging the SI and CGS units. Option C is correct because 1 Weber per square meter is by definition 1 Tesla. These consistent relationships validate that 'All of these' is the correct answer.

This relation is mathematically correct since 1 Weber per square meter is equivalent to a Tesla, which is equal to N m^-1 A^-1 in terms of derived units.

This relation is correct because 1 Tesla is exactly equal to 10,000 Gauss. Gauss is a CGS unit of magnetic flux density, whereas Tesla is the SI unit.

This relation is correct since 1 Weber per square meter is the definition of 1 Tesla, both representing the same quantity of magnetic flux density.

This option is correct because all individual relations presented in options A, B, and C are true. Therefore, selecting 'All of these' correctly identifies that each given relation holds true.
