B. ANGULAR UNCONFORMITY
Explanation: Angular unconformities occur when older strata are tilted or folded and then eroded before younger, more horizontal layers are deposited on top — so the bedding planes are no longer parallel. Disconformities have parallel layers with a time gap; nonconformities are contacts where sedimentary rocks overlie igneous or metamorphic rocks.
