Explanation

the narrator's grandfather's advice significantly influences his actions. The advice, which encourages the narrator to 'overcome 'em with yeses, undermine 'em with grins, agree 'em to death and destruction', serves as a guiding principle for the narrator. It shapes his approach towards dealing with racial discrimination and societal expectations. The narrator often finds himself resorting to deception and subversion, as suggested by his grandfather, to navigate the oppressive society. However, the advice also causes internal conflict within the narrator, as he struggles to reconcile his personal identity with the societal roles imposed upon him. Therefore, the grandfather's advice plays a pivotal role in influencing the narrator's actions and his journey towards self-discovery.

Correct Answer: B)

Cu(NH\(_3\))4Cl\(_2\)

Explanation

A complex salt is a compound that contains a central metal atom or ion bonded to one or more molecules or ions. These molecules or ions are called ligands, and they can be neutral or charged. Complex salts are typically characterized by their formation of coordination complexes, where the ligands donate electron pairs to the metal ion, forming coordinate covalent bonds.

In the given options, Option B: Cu(NH\(_3\))4Cl\(_2\) is a complex salt. In this compound, the central metal ion is copper (Cu) surrounded by four ammonia (NH\(_3\)) ligands. The ammonia molecules act as ligands, donating their electron pairs to the copper ion, forming coordinate covalent bonds. The chloride ions (Cl\(_2\)) are the counterions that balance the charge in the complex.

Option A: KAl(SO\(_4\))\(_2\).12H\(_2\)O is an example of a double salt, not a complex salt. Option C: K\(_2\)S\(_2\)O\(_3\).5H\(_2\)O is a hydrated salt, and Option D: Mg(OH)Cl is a simple ionic compound. None of these options involve the formation of coordination complexes, so they cannot be considered complex salts.
