The alleged management actions—interrogating, threatening, and dismissing employees for union support—violate:

The alleged actions violate employees’ rights to protected concerted activity (C) under the National Labor Relations Act (NLRA). At the SPHR level, protected concerted activity includes employees’ rights to organize, join, or support a union without employer interference, restraint, or coercion.

Interrogating employees about union activity, threatening adverse consequences, or terminating employees due to union support are classic unfair labor practices that directly interfere with these protected rights.

Weingarten Rights (B) apply to union-represented employees’ right to representation during investigatory interviews and are not relevant here. Collective bargaining agreements (A) apply only after a union is certified. Good faith employee relations (D) is not a legal standard under the NLRA.

SPHR exam questions frequently test recognition of protected concerted activity violations, making this a high-probability concept.
