State in each case, whether the given statement is true or false :
If B is the set of all consonants , then ` c in B. `

Answer

To determine whether the statement "If B is the set of all consonants, then c ∈ B" is true or false, we can follow these steps:

### Step 1: Define the set B
The set B consists of all consonants in the English alphabet. The English alphabet has 26 letters: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z.

### Step 2: Identify the vowels
The vowels in the English alphabet are A, E, I, O, and U.

### Step 3: List the consonants
To find the consonants, we exclude the vowels from the alphabet. The consonants are:
B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y.

### Step 4: Check if 'c' is in the set B
Now, we need to check if the letter 'C' is included in the set of consonants we listed.

From our list of consonants, we see that 'C' is indeed present.

### Conclusion
Since 'C' is a consonant and is included in the set B, we can conclude that the statement "c ∈ B" is true.

### Final Answer
The statement is **True**.
