Phrase: Riemann integral | Statement: [Henstock–Kurzweil integral, extends, Riemann integral]

Target entity: Riemann integral
Context triple: [Henstock–Kurzweil integral, extends, Riemann integral]

• A. Riemann integral chosen
  The Riemann integral is a fundamental concept in calculus that defines the integral of a function as the limit of sums of function values over increasingly fine partitions of an interval.
• B. Riemann–Stieltjes integral
  The Riemann–Stieltjes integral is a generalization of the Riemann integral in which integration is taken with respect to a function of bounded variation rather than just the identity function, allowing more flexible treatment of sums and distributions.
• C. Henstock–Kurzweil integral
  The Henstock–Kurzweil integral is a highly general integration theory that extends and refines the Riemann integral, capable of integrating a broader class of functions while retaining many of the intuitive properties of Riemann integration.
• D. Riemann sums
  Riemann sums are a fundamental method in calculus for approximating the area under a curve by summing the areas of a sequence of rectangles, forming the basis of the definition of the definite integral.
• E. Riemann–Liouville integral
  The Riemann–Liouville integral is a fundamental operator in fractional calculus that generalizes the concept of an n-fold repeated integral to non-integer (fractional) orders.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
