Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.
<h3 /><h3>What is the Hypothesis?</h3>
Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

The Law of Superposition.
The Law of Superposition states that each layer is younger than the one beneath it.
The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
At a glance this one's confusing, I agree.
Genetic engineering has made it easier for forensic scientists to differentiate human DNA beyond simple blood sampling. This inevitable led to release of innocent accused prisoners.
