Answer:
The correct answer is: Self-reflection.
Step-by-step explanation:
Self-reflection is one of the parts of the self-regulation cycle and can be understood as the capacity that individuals have to accurately evaluate themselves to learn more about their true nature.
Self-reflection aids the individual because it helps him/her correctly acknowledge his/her shortcomings and what possible steps he/she may take to improve or master a specific ability or task.
In this particular case, an individual who increases study time to improve one's science grade is demonstrating self-reflection because he is becoming aware that his grades could improve if only he put more time into his studies. He is correctly assessing his reality and taking steps to change it.
The correct answer is: Self-reflection.
