Tension and surface tension have

Spot out the odd one.

Speed of light in vacuum is given by $3 \times 10^8\, m\, s^{-1}$ in $MKS$ system. If in a new system, the unit of length and time is increased by a factor of $2$ and $4$, respectively, then the numerical value of speed of light in this new system will be
