Analytical Method:
Some tools are letters (I) + All letters are stars (A) = I + A = I = Some tools are stars (I).
Now, All phones are tools (A) + Some tools are stars (I) = A + I = No conclusion.
But the possibility in I exists.
Hence conclusion I follow.
Again, all phones are tools (A) + Some tools are letters (I) = A + I = No conclusion.
Hence, conclusion II does not follow.
Hence, option A is correct.
