Answer:Option III Easy Explanation by SamagraCS Team:
Definition:Basic COCOMO can be used for quick and slightly rough calculations of Software Costs.
Basic COCOMO model takes the formE = ab(KLOC)bbD = cb(E)db
Note: where E is effort applied in Person-Months, and D is the
development time in months. The coefficients ab, bb, cb and db are
given in table
E = 2.4(KLOC)1.05 Per Month
So, Option(III)is correct.
