Phrase: heterotic–M-theory duality | Statement: [E8×E8 heterotic string theory, dualityRelation, heterotic–M-theory duality]

Target entity: heterotic–M-theory duality
Context triple: [E8×E8 heterotic string theory, dualityRelation, heterotic–M-theory duality]

• A. T-duality
  T-duality is a fundamental symmetry in string theory that relates physically equivalent descriptions of strings propagating on compact spaces of different radii, often exchanging winding and momentum modes.
• B. heterotic supergravity
  Heterotic supergravity is the low-energy effective field theory of heterotic string theory, combining ten-dimensional supergravity with non-abelian gauge fields in a way that allows anomaly cancellation via the Green–Schwarz mechanism.
• C. M-theory chosen
  M-theory is a proposed unifying framework in theoretical physics that generalizes string theories into an eleven-dimensional model aiming to reconcile quantum mechanics with gravity.
• D. E8×E8 heterotic string theory
  E8×E8 heterotic string theory is a ten-dimensional string theory whose gauge symmetry is based on the product of two exceptional Lie groups E8, making it a leading candidate for unifying gravity with the forces and particles of the Standard Model.
• E. Montonen–Olive duality
  Montonen–Olive duality is a conjectured symmetry in certain gauge theories, especially N=4 supersymmetric Yang–Mills, that exchanges electrically charged particles with magnetic monopoles and relates strong coupling to weak coupling.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
