 In some species that use haploid-diploid mechanism of sex determination, such as some insects and some fish, the sex of an individual can be influenced by environmental factors, particularly temperature. For example, in some species of reptiles, the temperature at which the eggs are incubated can determine whether the offspring will be male or female. In other species, the ratio of haploid to diploid individuals can be influenced by temperature or other environmental factors. Thus, the assertion is true, and the reason correctly explains how temperature can affect the development of haploid and diploid individuals in some species that use haploid-diploid sex determination.

Option a is the correct answer.
