The null hypothesis can be rejected when the p-value is less than the level of significance (usually set at 0.05 or 0.01). So, if the p-value is less than 0.05 or 0.01, the null hypothesis can be rejected, and the alternate hypothesis can be accepted. Option A indicates that the p-value is less than a value that is not given, but this is assumed to be less than 0.05 or 0.01.
