$\begin{array}{1 1}(A)\;3500\\(B)\;3600\\(C)\;3700\\(D)\;3800\end{array} $

The word DAUGHTER consists of 3 vowels and 5 consonants

2 vowels and 3 consonants may be selected in $3C_2\times 5C_3$ ways

$\Rightarrow 3C_1\times 5C_2$ ways

$\Rightarrow \large\frac{3}{1}\times \frac{5\times 4}{1\times 2}$

$\Rightarrow 30$ ways

5 letters can be arranged in 5! ways or in $5\times 4\times 3\times 2\times 1$

$\Rightarrow 120$ ways

$\therefore$ Number of words formed by 2 vowels and 3 consonants which are selected from the word DAUGHTER

$\Rightarrow 30\times 120$

$\Rightarrow 3600$

Hence (B) is the correct answer.
