Which missing lines 02 and 03 return the correct count?

A developer wants to iterate through an array of objects and count the objects and count the objects whose property value, name, starts with the letterN.

Const arrObj = [{“name”: “Zach”}, {“name”: “Kate”},{“name”: “Alise”},{“name”: “Bob”},{“name”: “Natham”},{“name”: “nathaniel”}

Refer to the code snippet below:

01 arrObj.reduce(( acc, curr) => {

02 //missing line 02

02 //missing line 03

04 ). 0);

Which missing lines 02 and 03 return the correct count?
A . Const sum = curr.startsWith(‘N’)? 1: 0;Return acc +sum
B . Const sum = curr.name.startsWith(‘N’)? 1: 0;Return acc +sum
C . Const sum = curr.startsWIth(‘N’)? 1: 0;Return curr+ sum
D . Const sum =curr.name.startsWIth(‘N’)? 1: 0;Return curr+ sum
