Final answer:
Guerrilla marketing is about innovative and low-cost promotional strategies that create high impact. It involves surprising and unconventional methods to generate buzz and gain attention.
Step-by-step explanation:
Guerrilla marketing refers to creative, catchy, and low-cost promotional strategies used by companies to advertise their products or services. It is not about attacking competitors (A) or secret marketing initiatives (C), nor is it specifically about entrepreneurs who are hands-on marketers (D). This type of marketing often involves unconventional approaches aimed at achieving maximum impact through surprise, creativity, and ingenuity, often with a limited budget. For example, a company might use flash mobs, viral videos, or creative outdoor installations to generate buzz and word-of-mouth publicity.
