Answer 2

The answer to this question will be option C, Both I and II follow.

• Here we have statements that 'Some electricians are plumbers.' and that 'All plumbers are mechanics.'
• Now, conclusion I says, some mechanics are electricians or plumbers.
• This is true since some electricians are plumbers and all plumbers are mechanics. Thus, some mechanics are electricians or plumbers.
• Hence, conclusion I follows.
• Now, conclusion II says, 'Not all electricians are mechanics.​'
• This is also true since not all electricians are mechanics. Only some electricians are plumbers and all plumbers are mechanics.
• Thus, only some electricians are mechanics.
• Hence, conclusion II follows.
