Final answer:
None of the real estate advertisements described in the San Jose newspaper question are overtly illegal under Californian law, as they do not contain discriminatory language or preferences, which is required for compliance with state and federal regulations.
Step-by-step explanation:
The student's question relates to identifying which of the four real estate advertisements in a San Jose newspaper is illegal under Californian law. Per the Fair Housing Act and California state laws, it is illegal for housing advertisements to include language that indicates a preference, limitation, or discrimination based on factors such as race, color, religion, sex, handicap, familial status, or national origin.
Therefore, none of the described advertisements are overtly illegal based on the provided descriptions, as none of them seem to express discriminatory preferences or limitations. To ensure legality, real estate advertisements must comply with both state and federal laws by avoiding any discriminatory language or implications.
