Why does obtaining a C-13 NMR spectrum require a more sensitive instrument compared to an H NMR spectrum?
A) Due to the lower natural abundance of carbon-13 isotopes
B) Because carbon-13 nuclei have a lower gyromagnetic ratio than hydrogen nuclei
C) The larger chemical shift range of carbon-13 nuclei necessitates higher sensitivity
D) Carbon-13 nuclei have a lower nuclear spin quantum number than hydrogen nuclei
