The correct option is:

A weak, subsurface, clay layer failed, resulting in numerous landslides.

Explanation:

In 1964, the earthquake in Alaska damaged the Turnagain Heights and this earthquake was the strongest earthquake in the USA that was recorded. The magnitude was of about 9.2 on Richter Magnitude Scale.The statement is valid for the damage of Turnagain Heights which says that "A weak, subsurface, clay layer failed, resulting in numerous landslides." as it was the primary cause.The statement "It was hit by a large tsunami and then buried by a rock avalanche" was not the reason of it. The earthquake led to the Tsunami which increased the scale of destruction.The statement " It burned in a fire set off by broken gas lines." is also not valid as it was not cause of damage of Turnagain Heights. The gas lines broke due to the earthquake.
