Answer:
b. the action is not allowed.
Step-by-step explanation:
Traffic signs are established rules and regulations designed to direct and guide commuters and other road users.
A red circle and diagonal slash on a sign simply means that the action is not allowed.
A hortatory technique is focused on encouraging, exhorting and urging people to do that which is right, acceptable and worthy of emulation by others.
For example, commuters and road users are being urged not to litter the highway with thrash, waste, or dirt, in order to protect the planet from environmental degradation and pollution. This would help in conserving and mitigating risks posing as a threat to our dear planet and habitat.
Hence, a hortatory technique in policy implementation and enactment is primarily aimed at appealing to the sense and conscience of individuals, to engage in socially responsible acts.
