Explanation
The term IQ stands for "intelligence quotient" and refers to scores generated by several different tests and methods which measure a person's cognitive ability and intellectual potential. Research in this field regarding the genetic and environmental influences on intelligence has long been the subject of academic and scientific debate. Current research provides clear evidence that suggests both genetic factors and environmental factors contribute to an individual's intellectual development. However, the extent of genetic and environmental influences may differ. Likewise, interpretation of which factor plays a more key role also varies from person to person. Regarding the mentioned options:Option (a) and (b) contradicts the modern stance on the nature vs nurture debate in psychology, it dismisses the role of either pediatric exposure (a), or genetic influences (b) which is incorrect. Intellectual development is influenced by a mix of both these factors. Option (d) is likely false, as monozygotic twins, because derived from the same fertilized egg, typically have identical genetics or genotype, making them nearly genetically identical.Option (c) aligns with the current state of scientific understanding on the topic. Genetic factors indeed play a pivotal role in intellectual advancement.
