Correct Answer: B

Rationale: The correct answer is B: Rice cereal. Rice cereal is typically the first solid food introduced to infants because it is easy to digest and unlikely to cause an allergic reaction. Starting with rice cereal helps assess the baby's readiness for solid foods and reduces the risk of allergic responses. Choice A (Meat) is not recommended as the initial solid food due to its higher allergenic potential. Choices C (Fruits) and D (Vegetables) are also not usually recommended as the first solid food, as they may be more challenging for infants to digest compared to rice cereal.

Choice B is incorrect because it does not provide a specific timeframe for the closure of the fontanel. Choice C is incorrect as it suggests a later closure timeframe than usual. Choice D is incorrect as it states that the soft spots should have closed already, which is inaccurate for a 6-month-old infant.
