Which aspect is NOT a requirement for someone to be a surrogate?

The correct choice indicates that having a stable job is not a requirement for someone to be a surrogate. Surrogacy regulations can vary significantly by jurisdiction, but generally, the primary focus is on the surrogate's health, experience with pregnancy, and emotional readiness, rather than on their employment status.

Having had previous pregnancies without complications is often required to ensure the surrogate's health and capability to carry another pregnancy. Similarly, being at least 25 years old and having established a relationship with the intending parents for a certain duration is also common to help ensure the surrogate is mature enough to understand the commitment involved and has a degree of trust and rapport with the intended parents. Employment status, while it might be advantageous for the personal circumstances of the surrogate, is typically not a formal requirement in the surrogacy process.
