What can be inferred from this excerpt from Oliver Twist by Charles Dickens?

Occasionally, when there was some more than usually interesting inquest upon a parish child who had been overlooked in turning up a bedstead, or inadvertently scalded to death when there happened to be a washing—though the latter accident was very scarce, anything approaching to a washing being of rare occurrence in the farm—the jury would take it into their heads to ask troublesome questions, or the parishioners would rebelliously affix their signatures to a remonstrance.

a.Workhouse authorities were extremely careless in their duties.
b.Parishioners wrongly criticized parish officials.
c.The legal system carefully monitored parish affairs.
d.Parish children were extremely weak due to poor nourishment.
