12 consonants and 5 vowels
~ Taking 4 consonants and 3 vowels in each word
= 12C4 X 5C3
= 495 X 10
= 4950
Now 4950 words can also be arranged.
~ So these words can be arranged in 7! ways
= 4950 X 7!
Answer = (c) 4950 X 7!

Question Analysis:
We are given 12 consonants and 5 vowels, and we need to find the number of different words that can be formed by taking 4 consonants and 3 vowels in each word. We have to determine the correct option from the given choices.

Solution:
To solve this problem, we can use the concept of combinations.

Step 1: Determine the number of ways to choose 4 consonants from 12.
The number of ways to choose 4 consonants from 12 can be found using the combination formula.
12c4 = 12! / (4! * (12-4)!)
= 12! / (4! * 8!)
= (12 * 11 * 10 * 9) / (4 * 3 * 2 * 1)
= 495

Step 2: Determine the number of ways to choose 3 vowels from 5.
Similarly, the number of ways to choose 3 vowels from 5 can be found using the combination formula.
5c3 = 5! / (3! * (5-3)!)
= 5! / (3! * 2!)
= (5 * 4) / (2 * 1)
= 10

Step 3: Determine the total number of different words.
Since we need to choose 4 consonants and 3 vowels for each word, the total number of different words can be found by multiplying the number of ways to choose consonants and vowels.
Total number of different words = 495 * 10
= 4950

Therefore, the correct option is (c) 4950 × 7!
