Which of the following statements are true regarding the effect of flame temperature on atomic absorbance and atomic emission spectroscopy?

i. varying the flame temperature by 10 k hardly affects the ground-state population of the analyte and would not noticeably affect the analyte signal in atomic absorption.
ii. varying the flame temperature by 10 k hardly affects the excited-state population of the analyte and would not noticeably affect the analyte signal in atomic emission.
iii. varying the flame temperature by 10 k affects the ground-state population of the analyte and will noticeably affect the analyte signal in atomic absorption.
iv. varying the flame temperature by 10 k affects the excited-state population of the analyte and will noticeably affect the analyte signal in atomic emission.
select one:

a. i and ii
b. iii and iv
