A.
10-1 kHz
B.
10-2 kHz
C.
10-3 kHz
D.
10-4 kHz

Solution:

Data:Period (T) = 100 ms = 100 × 10-3 sec = 0.1 secFormula:\({\rm{frequency\;}}\left( {\rm{f}} \right) = \frac{1}{{\rm{T}}}\)Calculation:\({\rm{f}} = \frac{1}{{\rm{T}}}\; = \frac{1}{{0.1}} = 10\;Hz\)\({\rm{f}} = \frac{{10 \times {{10}^3}}}{{{{10}^3}}} = {10^{ - 2}}{\rm{\;KHz}}\)
