Question
**Question 19:** In a sequence of horizontal strata, a feature such as a fault or igneous rock body (such as a dike) that cuts across the strata ______.

- A. must be older than the strata
- B. must be the same age as the strata
- C. must be younger than the strata
- D. could be older, younger, or the same age as the strata with equal probability
- E. must always be Precambrian in age

**Explanation:** This question is about determining the relative ages of geological features using principles of stratigraphy. 

- Option A suggests that the feature predates the strata, which would violate certain geological principles.
- Option B posits an improbable scenario under normal geological conditions.
- Option C aligns with the principle that intrusions or faults must be younger than the strata they cut through.
- Option D offers an equal probability approach, which generally does not apply to geological formations.
- Option E imposes a specific ancient age on the feature, unrelated to its geometric relationship with the strata.

This question assesses understanding of geological dating principles essential to the field of geology and earth sciences.
