Q-1. The Software Maturity Index (SMI. ANSWER IS A

Ref. Software Maturity Index : (A metric in IEEE 982.1-1988, see http://www.standards.ieee.org/reading/ieee/std_public/description/se/982.1-1988_desc.html) M = number of modules in current version A = number of added modules in current version C = number of changed modules in current version D = number of deleted modules in current version compared to the previous version SMI = (M - (A + C + D)) / M More perspicuously, SMI = 1 - N/M, where M is the total number of modules in the current version of the system and N is the number of modules added, changed or deleted between the previous version and this one. SMI can be a measurement of product stability, when SMI approaches 1.0 the product is stable. When correlated with the time it takes to complete a version of the software, you have an indication of the maintenance effort needed.

Q-2. 

Answer is D
    Watson and felix model provides an relationship between delivered source lines of code L  and effort  E(person-month)and is given by equation -
    E = 5.2 L0.91
    Similarly duration of development D in months is given by
    D=4.1 L0.36
    Quick Fix model is  an adhoc approach to maintaining software. It is a fire fighting approach, waiting for the problem to occur and then trying to fix it .
    Putnam model describes the time and effort required to finish a software project of specified size.
    Logarithmetic Poisson Model  It is software reliability model that predicts expected failures (and hence related reliability quantities).
