Physical quantities and units

Which of the following correctly expresses a derived SI unit in terms of SI base units?

$m2s−3A−1\text{V} = \text{kg m}^2 \text{s}^{-3} \text{A}^{-1}$

$m2s−2A−2\Omega = \text{kg m}^2 \text{s}^{-2} \text{A}^{-2}$

$s−2A−1\text{T} = \text{kg m s}^{-2} \text{A}^{-1}$

$F=kg−1m−2s3A2\text{F} = \text{kg}^{-1} \text{m}^{-2} \text{s}^3 \text{A}^2$
