B. FALSE

Answer: B

Explanation:

A column with very low cardinality (e.g. a column that indicates only whether a person is male or female) might yield only minimal pruning. At the other extreme, a column with very high cardinality (e.g. a column containing UUID or nanosecond timestamp values) is also typically not a good candidate to use as a clustering key directly.
