For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Bell numbers | Statement: [enumerative combinatorics, usesConcept, Bell numbers]

Target entity: Bell numbers
Context triple: [enumerative combinatorics, usesConcept, Bell numbers]

• A. The Twelvefold Way
  The Twelvefold Way is a framework in combinatorics that systematically classifies twelve fundamental ways of counting functions between finite sets under various labeling and structural constraints.
• B. Delannoy
  Delannoy is a French surname, often associated with historical figures and families of French or Flemish origin.
• C. Bernoulli numbers
  Bernoulli numbers are a sequence of rational numbers that play a central role in number theory and analysis, especially in formulas for sums of powers of integers and in the study of special functions like the Riemann zeta function.
• D. Pascal's triangle
  Pascal's triangle is a triangular array of numbers in which each entry is the sum of the two directly above it, widely used in combinatorics, algebra, and probability.
• E. Pochhammer symbol
  The Pochhammer symbol is a mathematical notation representing rising factorials, widely used in series expansions, special functions, and hypergeometric functions.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
