00:05Question says, per second is the unit of A time period, B velocity, C frequency, D conductance.
00:17The unit of time period is second, the unit of velocity is meter per second, the unit of conductance is
00:26per ohm or Siemens, the unit of frequency is per second, because frequency is the reciprocal of time period, so
00:40the correct option is C frequency.
00:45Question sense.
