In order to diagnose if variables other than Y (dependent variable) jump at the cutoff, one must use which of the following equations: A) Y_i=B₀+B1T_i+B2(X_1i-C) +B3(X_1i-C) T_i +e_i B) Y_i=B₀+B1T_i+B2(X_1i-C) +B3(X_2i) T_i +e_i C) X_2i=g₀+g1T_i+g2(X_1i-C) +v_i D) X_i=B₀+B1Y_i+B2(Y_i-C) +B3(X_2i) T_i +e_i

To diagnose if variables other than the dependent variable (Y) change at the cutoff, one should use a regression discontinuity design (RDD) approach focusing on those other variables as the outcomes. Choice C represents an equation where X (a variable other than Y) is modeled as a function of the treatment indicator (T), the running variable (X-C), and other terms, which is appropriate for checking if X jumps at the cutoff, indicating a violation of the RDD assumptions.
