B. Systematic

Step-by-step explanation:

Since Quality Control Manager is selecting every 10th soup. This type of Sampling Method is called Systematic Sampling.

Further,

If the whole population is divided into many groups (strata) such that between the group units are heterogeneous and within the group units are homogeneous then units are randomly selected from these groups. This type of sampling is called Stratified Sampling.

If the sampling is done by any criteria then this type of sampling method is called Systematic Sampling. Like observer is taken every 5th unit as a sample.

If the samples from the population are chosen randomly, where each and every unit has an equal chance of selection in a sample. This type of sampling is called Simple Random Sampling.

In Cluster Sampling the population is distributed into a distinct group (clusters) and one or more groups (clusters) are chosen as a sample then it is Cluster Sampling.

If the observers collect the sample as his/her convenience, then this type of sampling method is called Convenience Sampling.
