B. 1.72

C. 17.2

D. 172

Answer: Option C

Solution(By Examveda Team)

$$\eqalign{ & \frac{{29.94}}{{1.45}} \cr & = \frac{{299.4}}{{14.5}} \cr} $$
  $$ = {\frac{{2994}}{{14.5}} \times \frac{1}{{10}}} $$    [Here, Substitute 172 in the place of $${\frac{{2994}}{{14.5}}}$$ ]
$$\eqalign{ & = \frac{{172}}{{10}} \cr & = 17.2 \cr} $$
