Who expressed concern about the law stating that if Jacobs hangs for witchcraft, he would forfeit his property?

The correct answer is associated with Giles Corey, who is deeply concerned about the implications of being executed for witchcraft, specifically the loss of his property. In the context of the play, Giles understands that if he is convicted and hanged, his land would be confiscated by the state and given to others. This demonstrates his awareness of the manipulation of the court system and the greed that drives many of the accusations in Salem. Giles's preoccupation with retaining his property highlights the broader themes in "The Crucible" regarding personal integrity, materialism, and the consequences of the hysteria that overtakes the community.

Reverend Hale expresses concern over the morality of the witch trials but is not specifically tied to the issue of property loss. John Proctor does struggle with the implications of the trials and seeks to reclaim his sense of integrity but does not explicitly articulate the concern over property forfeiture. Deputy Governor Danforth, on the other hand, is more concerned with maintaining his authority and the legitimacy of the court rather than individual property rights. Therefore, Giles Corey's focus on the fate of his property provides insight into his character, blending personal stakes with the larger societal issues presented in the play.
