A bar magnet's magnetic field strength is $B = 0.1\ \text{T}$ near its pole. The SI unit of magnetic field strength is the tesla. Which statement correctly relates the tesla to base SI units?

$1\ \text{T} = 1\ \frac{\text{kg}}{\text{A} \cdot \text{s}^2}$

$1\ \text{T} = 1\ \frac{\text{N}}{\text{C}}$

$1\ \text{T} = 1\ \frac{\text{V}}{\text{m}}$

$1\ \text{T} = 1\ \frac{\text{J}}{\text{C} \cdot \text{m}}$
