Availability can be calculated using the following formula:

Availability = MTBF / (MTBF + MTTR)

Substituting the given values, we get:

Availability = 218 / (218 + 14) = 0.9399 or 93.99%, which can be rounded off to 94.0%.

Therefore, the best choice is A, which corresponds to an availability of 94.0%.
