Option A: 4 is the solution
Explanation:
The given expression is 
We need to determine the solution of the expression.
<u>Solution:</u>
The solution of the expression can be determined by solving the expression for t.
Let us solve the given expression.
Applying the log rule, if
then 
Thus, we have;

Adding both sides of the equation by 4t, we get;

Adding both sides of the equation by 3, we have;

Dividing both sides of the equation by 5, we get;

Hence, the value of t is 4.
Therefore, the solution of the given expression is 4.
Thus, Option A is the correct answer.
