Phrase: Euler product | Statement: [Riemann’s Zeta Function (book), covers, Euler product]

Target entity: Euler product
Context triple: [Riemann’s Zeta Function (book), covers, Euler product]

• A. Euler product formula for the Riemann zeta function chosen
  The Euler product formula for the Riemann zeta function is a fundamental identity in analytic number theory that expresses the zeta function as an infinite product over all prime numbers, revealing a deep connection between primes and the distribution of integers.
• B. Euler’s identity for sine product
  Euler’s identity for sine product is a classical formula expressing the sine function as an infinite product, foundational in the theory of infinite products and special functions.
• C. Wallis product
  The Wallis product is an infinite product formula for π/2, discovered by John Wallis in the 17th century and notable as one of the earliest infinite product representations of π.
• D. Riemann zeta function
  The Riemann zeta function is a complex-valued function central to analytic number theory, whose properties—especially the distribution of its zeros—are deeply connected to the distribution of prime numbers.
• E. Dirichlet series
  A Dirichlet series is an infinite series of the form ∑ aₙ/nˢ, fundamental in analytic number theory for studying arithmetic functions and L-functions.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
