Correct answer - A Increased rainfall.

Why? - Intense storms and heavy rainfall can flood roosts, killing entire colonies of bats trapped in caves or mines. Early season snow and prolonged freezing temperatures have also killed bats by blocking cave entrances with snow drifts and ice, or causing bats to freeze to death within their roosts during hibernation.
