The life cycle you described corresponds to option B: haploid sexual life cycle.
In many fungi, the dominant phase of the life cycle is the haploid phase. The steps you've outlined indicate that the organism starts as a diploid zygote, undergoes meiosis to produce haploid germ cells, which develop into haploid adults. These adults then undergo mitosis and produce sexual spores, which can combine to form a new diploid zygote, completing the cycle.
This contrasts with the diploid sexual life cycle (option C), where the diploid phase would be the dominant stage, or binary fission (A), which is an asexual reproduction method, or alternation of generations (D), which typically involves both haploid and diploid phases, but not in the way described in your sequence.
