We can use the formula:
(change in length) = (coefficient of linear expansion) × (original length) × (change in temperature)
Let's assume the original length of the wire to be 100 units. 
So, 0.1% increase in length means the change in length = 0.1 units.
Now, let's substitute the given values in the formula:
0.1 = (16.6 × 10^-6) × (100) × (change in temperature)
Simplifying, we get:
change in temperature = 0.1 / (16.6 × 10^-6 × 100) = 0.6°C = 60.2°F
Therefore, the correct answer is B.
