Solution

The correct option is B inversely
Frequency is the number of the waves (crests and troughs) produced in a unit time (second).

Time period is the time required to produce one complete wave (crest and trough).

From these definition, it can be concluded that time period is inversely proportional to frequency.
$T = \frac{1}{f}$
