Solution:
Out of 7 different consonants, we can select 2 in 7C2 ways = 21 ways.
Out of 3 different vowels, we can select 1 in 3C1 ways = 3 ways.
The vowel should lie between the 2 consonants. Therefore, we can arrange the selected consonants and the selected vowel in 2! ways = 2 ways.
Therefore, the total number of words that can be formed = 21 x 3 x 2 = 126.
Hence, the answer is option (a) 3 x 7 x 6.
