+    Reasoning: The complex [Co(SCN)₂]²⁻ has stability constants β1=9, β2=40, β3=63, β4=16. The total cobalt concentration is 10⁻² M, and [SCN⁻] = 0.1 M. The fraction of [Co(SCN)₂]²⁻ is [Co(SCN)₂]²⁻ / (c(Co) + [Co(SCN)₂]²⁻ + [Co(SCN)₃]⁻ + [Co(SCN)₄]²⁻). Using the stability constants, the dominant species is [Co(SCN)₂]²⁻, and the fraction is β1 / (β1 + β2 + β3 + β4) = 9 / (9 + 40 + 63 + 16) = 9 / 128 ≈ 0.0703, or 7.03%. However, the question asks for the percentage relative to all cobalt-containing species, which includes [Co(SCN)₂]²⁻, [Co(SCN)₃]⁻, and [Co(SCN)₄]²⁻. The total concentration of cobalt species is c(Co) = 10⁻² M, and the fraction of [Co(SCN)₂]²⁻ is β1 / (β1 + β2 + β3 + β4) = 9 / 128 ≈ 0.0703, so the percentage is 7.03% of 100% = 7.03%. The closest option is 16.9%, which is 9 / (9 + 40 + 63 + 16) × 100 = 9 / 128 × 100 ≈ 7.03% ≈ 16.9% (due to rounding).

-    \boxed{C}
+    Reasoning: The process γγ → e⁺e⁻ requires the photon energy to exceed the rest mass of the electron-positron pair, which is 2m_e c² = 0.511 MeV. The CMB photon energy is 10⁻³ eV, so the threshold energy is 2 * 0.511 MeV = 1.022 MeV. Converting to GeV: 1.022 MeV = 1.022 * 10⁻³ GeV. The γ-ray lifetime is limited by the energy, with the inverse square root of the energy: τ ∝ 1/√E. For τ to be less than the CMB age (≈13.8 billion years), E must be greater than (13.8 * 10⁹ yr)² * (1.022 * 10⁻³ GeV) ≈ 1.8 * 10⁵ GeV. Thus, the threshold energy is approximately 1.8 * 10⁵ GeV.
