Step 1: Analyze the Code for NATION and EARN
NATION is coded as 467234. Let us map each letter to its corresponding number:
N = 4
A = 6
T = 7
I = 2
O = 3
N = 4
Similarly, EARN is coded as 1654:
E = 1
A = 6
R = 5
N = 4
Step 2: Apply the Same Coding Pattern to ATTENTION
Now we apply the same pattern for the word ATTENTION:
A = 6
T = 7
T = 7
E = 1
N = 4
T = 7
I = 2
O = 3
N = 4
Therefore, ATTENTION is coded as 677147234.
Final Answer: The correct code for ATTENTION is (D) 677147234.
