A price ceiling can often be viewed as:​

A) ​the government setting price above market equilibrium price.
B) an implicit tax on producers and an implicit subsidy to consumers.
C) ​the government setting price below market equilibrium price.
D) ​Both b and c

Price ceilings, when set below the market equilibrium price, act as an implicit tax on producers by limiting the price they can charge, effectively reducing their potential revenue. Simultaneously, they act as an implicit subsidy to consumers by allowing them to purchase goods or services at prices lower than what the market would typically dictate, hence both B and C are correct.
