(C) The number of ways to select $3$ consonants from $7$ is given by ${}^{7}C_{3} = \frac{7 	imes 6 	imes 5}{3 	imes 2 	imes 1} = 35$ ways.The number of ways to select $2$ vowels from $4$ is given by ${}^{4}C_{2} = \frac{4 	imes 3}{2 	imes 1} = 6$ ways.The total number of ways to select the $5$ letters is $35 	imes 6 = 210$ ways.Since these $5$ selected letters can be arranged among themselves in $5!$ ways,the total number of words is $210 	imes 5! = 210 	imes 120 = 25200$.
