Digital Marketing — Hard What is the concept of product-led growth (PLG) and how does it transform the relationship between marketing and product? A A product development methodology where the marketing team leads all product decisions B An approach where product teams manage marketing budgets directly without a separate marketing function C A growth hack where products are given away free to gain market share and premium subscriptions later D A go-to-market strategy where the product itself is the primary driver of acquisition, activation, retention, and expansion — the product's value drives word-of-mouth and viral loops (e.g., Slack, Dropbox); it transforms marketing from demand-generating gatekeeper to a team that amplifies product-led signals and optimizes the self-serve journey rather than relying purely on outbound sales Show explanation
